DISTEMPER.
ОглавлениеOf all the diseases to which the dog is subject, this one is the most dreaded. Writers have agreed it is the scourge of the canine race. Blaine and Youatt speak of it as capricious and untractable; the French regard it as incurable. The owners of dogs, despairing of benefit from regular means, have for a long time been content to trust in charms and specifics. Folly and cruelty have been embraced to accomplish that which kindness and science appear unequal to perform; and one general feeling seems to be entertained with regard to the distemper—most persons being agreed that the disorder is not to be subdued by medicine, and that its fatality is independent of the best efforts of man to check it.
My experience does not corroborate these various but harmonious accounts and opinions. In my conviction, the disorder is feared only because it is not understood, and is rendered worse by the injudicious attempts to relieve it. I find it tractable, easily mastered, and when submitted to me before the system is exhausted, I am very seldom disappointed by the result of my treatment. It has for some time been my custom to tell those who bring me an animal affected with this complaint, that if my directions are strictly followed, the creature "shall not die." When saying this, I pretend not to have life or death at my command, and the mildest affections will sometimes terminate fatally; but I merely mean to imply, that when proper measures are adopted, distemper is less likely to destroy than the majority of those diseases to which the dog is liable.
Distemper has been hitherto regarded as an inflammatory disorder, which was to be conquered only by antiphlogistic remedies. Bleeding, purging, vomiting, sedatives, blisters, and setons were employed; and the more acute the attack, the more violent were the means resorted to for the purpose of its conquest. Under such treatment I do not wonder at the evil character which the malady has obtained; for in proportion as the efforts made were great, so would be the probability of the disease proving destructive. There can be no doubt that more dogs have been killed for the distemper than would have died from it if nature had been suffered to take her course; and yet there is no disease that more requires help, or rewards the practitioner more largely for the assistance he affords.
The reader is entreated to dismiss from his mind all he may have read, or heard, or thought of this affection. Let the many tales about never-failing receipts, and the only proper modes of treatment, be for a time at all events forgotten, that the author, who undertakes to oppose prejudice and to contradict authority, may at least have a patient hearing. There is no reason to doubt that many cases which have been called distemper have, to all appearance, been saved by each of the reputed methods of cure. A pillet of tobacco, a tea-spoonful of salt, a dose of castor oil, an emetic, rubbing the nose with syrup of buckthorn, &c., &c., or anything that is famed for the purpose, may have often seemed to check the disease; but no one who has been accustomed to depend on these charms can deny he has frequently witnessed their failure. That they should sometimes have seemed to do good is easily explained. In the first place, there are very few persons who know how to recognise the early symptoms of the malady; but it is usual for every young dog that is a little poorly to be pronounced sick with the distemper.
The unfounded belief that all of these animals must have the disease makes every one anticipate its advent, and tempts them to call every ailment by the name suggested by their expectations. Two-thirds, at least, of the cases which are so quickly cured by nostrums and specifics would on inquiry prove to have been mistaken; and as, in the instances where a single dose is depended upon, nature is pretty much left to herself, the chances are that a fair share of the rest would get well of themselves. The recovery, however, could in no way be expedited by that which is credited for its accomplishment; since the little done is mostly calculated to aggravate and not to alleviate the symptoms, while there is no possibility it should eradicate the disorder.
In its character, distemper approaches very near to "continued fever" in the human subject; the chief difference being consequent upon the more delicate constitution and more irritable temperament of the dog, which prevents the two diseases from appearing exactly the same. It consists in a general fever, which produces a morbid excitement of all the mucous membranes. The digestive track is the principal seat of the disease, but of course its presence is most easily recognised at those parts which are most exposed to view. Thus the membrane of the eye, being a comparatively large surface, and by its delicacy well calculated to denote every variation of the system, is usually the first observed, and often the only place inspected. If this be cloudy or watery, the nature of the malady is at once concluded; the membrane of the nose also, though less palpable, is under observation; and if its secretion be copious and opaque, the fact is generally imagined to be established. The alterations, however, exhibited by these membranes are no more than sympathetic derangements, they being continuous with the more important organs; and when proofs are found in the eyes or nose, the disorder is generally confirmed, or has taken hold of the system. Some have supposed the disease originated in the nose, and thence extended to other parts; now I shall not stop here to consider so groundless an hypothesis. It essentially is fever affecting the entire of the mucous surfaces, but especially those of the alimentary canal.
The causes cannot be well ascertained. Contagion has been by the majority of writers supposed to be its principal source, but I cannot say my experience has corroborated that opinion. My own little cur never had the distemper, and yet she lived where the disease was scarcely ever absent. Animals virulently affected were daily brought to me, and not a few were left in my charge. From these she was not kept separate; they were her acquaintances and companions; she played with them, and often by choice shared their beds; and nevertheless she died without exhibiting the disease. I do not generally put those dogs by themselves which are affected with distemper; yet I cannot bring to mind the instance of an animal while under my care having caught the disorder. I doubt whether there is any justice in the general opinion. It would be hard to prove the prevailing notion was a prejudice, yet there can be no doubt that it is much more insisted upon than it deserves to be.
With regard to other causes, I know of none. I have not been able to observe that any circumstance can induce the disease, though at particular ages the animals are predisposed to its exhibition.
During the latter period of dentition—that is, when the second set of incisors are well up, and the permanent tusks are about half-grown, the temporary ones being still retained—is the time when pups are most disposed to display this disorder. I cannot state the precise age, because mouths are not regular in their appearances even as to mouths; but the aspect of the teeth will sufficiently mark the period when an individual may be expected to be attacked. The season certainly, in no little degree, influences the disease. In winter it is not usually seen; in the spring it is more common; in summer is rare, but less so than in winter. During the autumn, however, especially if much rain should fall, it is very frequent, and always more prevalent than at any other periods. Spring and autumn, therefore, are the times when it is to be looked for, but in the latter it is to be anticipated.
When treating of a subject like the present, there would seem to be a disposition to string together a number of words which do duty for information. Cold, wet, bad food, foul air, excessive exertion, fear, &c., are grouped together, and put forth for almost every "ill that flesh is heir to;" but I have to learn that these accepted terms have any connexion with the development of this disorder. Dogs that are starved, neglected, and cruelly tortured—animals that are judiciously fed, properly housed, and sensibly treated—as well as favorites that are crammed, nursed, and humored—all equally are its victims; and those which are most cared for fall most frequently, while those which are least prized more generally survive. If, therefore, privation or exposure be of any importance, the facts seem to infer their tendencies are either to check or mitigate the attack.
Exercise and food, however, do influence the complaint. The dog that is free suffers much less severely than the one that is confined. The animal that never tastes flesh has a much lighter attack than the one which subsists entirely upon meat. This last fact I have often proved. When the distemper has made its appearance, the opportunity for changing the diet has passed away. We have, then, only a choice of dangers. To remove the flesh to which the animal is accustomed is to cause it to pine and to weaken the strength, at a time when vigor is of every importance; whereas to continue the meat is mostly certain death; in this position I generally take away the flesh, for by so doing I give the patient a chance of recovery; and however desperate that chance may be, nevertheless it is to be much preferred to no chance at all.
The symptoms in the very early stage are not well marked or by any means distinguished for their regularity. They may assume almost any form; dulness and loss of appetite, purging, or vomiting, are very frequently the first indications. The more than usual moisture of the eyes, and a short cough, are often the earliest signs that attract attention. In the bitch a desire for copulation, with a disinclination to accept the dog, is to be regarded with suspicion; as is also a display of peevishness and a wish to be undisturbed in full-grown animals. These things denote no more than the derangement of the system; but if, conjoined with them, the inner surface of the lower eyelid should appear to be more red than usual, and the pulse should be increased in number without being materially altered in character—ranging from one hundred and twenty to one hundred and thirty in puppies, and in dogs from one hundred and ten to one hundred and twenty-five—the probability of distemper making its appearance is the greater, though even then by no means certain.
The period of the year, however, will also have to be taken into consideration; and inquiry should always be made whether any animals in the immediate neighborhood are known to have exhibited the disorder; because the disease is then proved to be in the locality. At this stage the practitioner is always more or less in the dark; and therefore he contents himself with such measures as he concludes are adapted to the symptoms, and waits for further instructions which nature will speedily develope.
When the disease is established, the animal is sensitive to cold. It seeks warmth, and is constantly shivering; when taken hold of, it is felt to tremble violently, so much so that the pulse cannot be accurately counted. The bowels are generally constipated. A thick purulent discharge flows from the eyes; and the white around the eye, if the upper lid be retracted, will be seen covered with numerous small and bright red vessels, giving to the part the appearance of acute inflammation. The vessels now spoken of are not to be confounded with the veins which are natural to this organ. These last are large, and of a purple hue, while their course is in the direction of the circumference of the cornea. The small vessels, indicative of distemper, are fine, bright in color, and their course is towards the centre, or in a line directly the opposite to that indicated by the veins. They are never present during health, though they are often to be witnessed in other diseases besides that which is here treated of. A glairy mucus, or yellow fluid, moistens the nostrils, and if the ear be applied to the head, the breathing will be discovered to be accompanied with an unusual sound. The cough is often severe and frequent; it is sometimes spasmodic—the fits being almost convulsive, and terminating with the ejection of a small quantity of yellow frothy liquid, which is thrown off by the stomach. The digestion is always impaired, and sickness is not unusual; the matter vomited having an offensive smell, and never being again consumed by the animal, as is generally the case when the creature is in health. The nose is dry and harsh; the coat staring and devoid of gloss: the skin hotter than is customary, and the paws warm. The pulse is perhaps quicker by twenty beats than during the prior stage, but less full—the artery feeling sharp, short, and thin under the finger.
When the symptoms described are apparent, the distemper is easily recognised, but it is not likely to continue stationary for any long period. In the course of a week it generally changes its character, and sometimes appears to subside altogether; the cases in which the disease steadily progresses, becoming day by day more severe, being comparatively rare.
When no abatement is witnessed, the case is not to be despaired of, but it requires to be anxiously watched; for often it will take a sudden turn, sometimes favorable, but more frequently demanding immediate assistance to prevent a fatal termination. The symptoms become aggravated. The eyes are clogged by a thick matter which glues the lids together, especially in the morning. The nostrils are plugged up by an accumulation of tenacious discharge, which becomes encrusted over the lips and nose, and impedes the breathing. The body rapidly wastes, though the appetite may return, and even be voracious. The shivering is constant. The dog seeks repose and is disinclined to move; though at times it may be playful, and in some instances will never exhibit any diminution of spirit. The cough may continue; but it more often ceases, or is only heard at irregular and distant intervals. The animal makes repeated and desperate efforts to expel the accumulated matter from the nose, and uses its paws evidently with an intention to remove the annoyance. Day by day, if not attended to, these signs grow more aggravated; the breath becomes very offensive; ulcers appear on the lips; the eyes become white; the discharge from the nostrils changes its color, and is mingled with blood and scabs, having an offensive odor. The creature at last begins to "yap," or utter short sharp cries. It becomes more weak, till at length it cannot walk, but lies upon its side; the noise being continued for hours, and then ceasing only to be again commenced. Constipation has usually been present, but at last diarrhœa sets in; the fæces have that peculiar smell which in the dog is characteristic of the latest stage of all; and gradually death, without a seeming struggle, closes the scene of suffering.
More frequently—indeed, in the majority of cases—the distemper is hardly well developed before it all at once seems to disappear. This peculiarity in the disorder has no doubt given strength to the general faith in specifics for this disease. The animal suddenly so far recovers, or appears to recover, after having been seriously affected, that the inexperienced naturally conclude the dog is either quite well, or evidently so far cured that the efficacy of the remedy administered is not to be disputed. For two or three weeks this deceptive appearance may continue, and in some cases no return of the symptoms may be witnessed; but in the majority of instances the disorder is only dormant, and again starts up as if it had been strengthened by its treacherous repose. The running from the nose comes back in excessive quantities, and either the bowels are singly inflamed, or with them the brain is involved, and fits or diarrhœa, or both united, speedily terminate in death, to arrest which medicine has seldom the power. The loss is on these occasions rarely attributed to distemper, which is thought to have been subdued; but death is commonly set down to fits, or to poison, or to inflammation of the bowels, or to anything else which the imagination of the proprietor may conceive. Hence we get an insight into the value of a large number, and perhaps into all, of the reputed nostrums; and hence it is the more necessary the reader should be made aware of those indications which denote the virus is not eradicated, but only latent as it were, lurking, to spring with greater certainty upon its victim. No one must conclude the distemper is mastered if the dog continues to lose flesh, or if the animal does not rapidly repair the waste consequent upon the earlier stages of the disorder. This tendency to stand still or decline should be carefully observed, and it will seldom deceive. When it is remarked, or even suspected, let the owner be upon his guard. When the distemper is actually overcome, there is a marked disposition to fatten; indeed, so strong is it at this time that, should it not be evident, there can be no doubt as to the cause, especially if a short and slight attack of the disorder has been known to have occurred a little time before. A warning, equally clear to those who will look for and can read it, is to be obtained from the eyes. These may be bright, and even peculiarly transparent; the face have a more animated expression than it displayed during previous health; but if the eyelids are retracted, the membranes will be found red, and the vessels before observed upon will be seen running over the white of the eye. When these things are present, although the coat may be beautifully smooth, the discharge dried up, the shivering gone, the appetite strong, and the spirits boisterous, still there is in the system the seeds of a disease which at no distant period will reappear in its most dangerous form.
Commonly, after the second stage, there is an abatement of the symptoms, without any actual cessation in the discharges. The dog is concluded to be better, and thought to be doing well, but it will not be long before something to excite alarm is witnessed. The eyes or nerves, or lungs or liver, or stomach or intestines may be attacked; or a pustular eruption, or actual mange, or a disposition in the animal to eat its own flesh, or chorœa, or paralysis may appear, and all of these possible varieties require to be separately dwelt upon.
The eyes lose their transparency, the surface is white and opaque, the sight is impaired, and the lids are nearly constantly closed. One or both of the organs of vision may be thus affected; usually the two are simultaneously affected, but seldom with the like intensity. After a few days, and sometimes at the commencement, a small circular depression is to be seen upon the very centre of the eyeball. It is round, and varies in size from that of a pin's head to that of a small pea, but rarely becomes larger. The depression, if nothing be done to check it, deepens till a little shallow pit is exhibited. At other times the hole grows larger and deeper, till the outer covering of the eye is absorbed, or, in common phrase, is eaten through, and the water escapes: this gives relief. If, however, the animal survives, the eye is often perfectly restored, though very frequently a white speck marks the spot which was ulcerated; or the dog is left with weakened eyes, and has a tendency to cataract, which may ultimately render it blind.
The affection of the lungs is denoted by the dog breathing more quickly, and often making a small plaintive or whistling noise during respiration. Though cough is quite as often absent as present; but if present it is usually severe; the pulse is increased, but small and thready, and the appetite may not be impaired. The animal is, however, disinclined to move, if put down at liberty, it always gets into some place where it hopes to be allowed to remain undisturbed. As the symptoms become more intense, the animal constantly sits upon its haunches; but I have not seen it carry the head erect, although authors state this to be one of the indications. There is a desire for fresh air, and the dog will always leave the house, or get to the window or door, if he have an opportunity of so doing. These signs are hardly to be mistaken, but they are easily confirmed. If the ear be applied to the side of a healthy dog's chest, no sound can be detected; but when the lungs are diseased, a very plain noise is readily heard. The presence, therefore, of any murmur, or of anything like air escaping over a dry rough surface, is indicative of disease, and the certainty that the lungs are involved is confirmed.
Dogs of late years have not commonly died of pneumonia during the distemper; but authors speak of the pulmonary form of the disorder as having formerly been a common cause of death. I know it only as a mild variation of the ordinary symptoms. It has not in any case under my observation proved fatal, but has readily yielded to gentle measures, aided by attention to simple diet.
The liver is generally involved. After the termination of a fatal case, this gland is found either soft or more brittle than it ought to be, else it is discovered much enlarged. I never saw it of less than its natural size. Generally it is discolored, mostly of a pale tint; which sometimes exists all over the organ, though the pendulous edges of the lobes are very generally seen of the bright red, suggestive of inflammation. The gall-bladder is always distended with a thin dark-green fluid or impure bile; and a large quantity of the same secretion, but of greater consistency, is distributed over the lining membrane of the anterior intestines. The liver obviously is the cause of the yellow distemper, which is no more than jaundice added to the original and pre-existing disease. Yellow distemper is by writers treated of as a distinct disorder, but I have not yet met with it in that form. When it has come under my notice, it has been no more than one of the many complications which the symptoms are liable to assume. The dog has been ill before his skin became discolored; but the eyes not exhibiting that ordinary discharge which denotes the true character of the affection under which he labored, the distemper was not detected.
Everything concerning distemper is by the generality of the public misunderstood. Most people imagine a dog can have the distemper but once in its life; whereas I had a patient that underwent three distinct attacks in one autumn, that of 1849. The majority of persons who profess an intimate knowledge of the dog will tell you distemper is a disorder peculiar to the young; whereas I know of no age that is exempt from its attack. I have known dogs, high-bred favorites, to be left with men selected because of their supposed familiarity with dog diseases; and these very men have brought to me the animals in the fits which are the wind-up of distemper, yet notwithstanding have been ignorant that their charges had any disease whatever. All the stages and symptoms of ordinary distemper may appear and depart unnoticed; but it is widely different with yellow distemper, for when the yellowness appears, it is so marked that no description of a peculiar symptom need be inserted, since it cannot be overlooked or mistaken. It is attended with excessive debility, and, unless properly combated, is rapidly fatal.
The stomach and intestines are always involved; I have never known a case in which either escaped. The affection of the first is generally shown by sickness during the earliest stage; when also the derangement of the last is denoted by either costiveness or relaxation, the bowels never being perfectly regular; towards the latter stages, or about the third or fourth week, the appetite sometimes becomes enormous; the craving for food is then unnatural, and is so intense that no quantity can appease the hunger. The animal will eat anything; dry bread is taken with avidity, and stones, cinders, straw, and every species of filth are eaten with apparent relish. Such, however, is not always the case, since it is not unusual for the appetite entirely to fail. In either instance the dog rapidly wastes; the flesh seems to melt as it were away, and the change produced by a few days is startling; from having been fat, a thinness which exposes every bone is witnessed in a shorter time than would be supposed possible. At this period vomiting may come on; but when the animal is morbidly ravenous, the stomach does not generally reject its contents. After death I have found it loaded with the most irritating substances, and always acutely inflamed; but no sickness in any instance of this kind has been observed. Vomiting is most generally absent, but the protruded and reddened appearance of the anus will give a clue to the actual condition of the alimentary tube. The stomach is inflamed, not throughout, but in various parts which are in different stages of disease. The pyloric orifice is always more affected than the cardiac; the duodenum, jejunum, and ileum, are inflamed; the cæcum is enlarged, inflamed, and generally impacted. The rectum, however, suffers most severely; it is much reddened and thickened, often to an extraordinary degree. I have known blood to be exuded from the surface of this bowel in such quantities as to destroy the life from actual hemorrhage. In one case, however, a spaniel vomited more than half-a-pint of blood previous to its death, which took place two hours afterwards. A small quantity of blood is ordinarily passed with the fæces toward the latter stage; but in several cases a large amount of pure blood, partly coagulated and unmingled with any fæcal matter, has flowed from the body in a continued stream, to which there will be cessation only as death approaches. The possibility of this occurring will give the reader some idea of the extent and degree in which the bowels are or may be diseased; the symptoms, nevertheless, are not such as would suggest the danger which may be shortly violently exemplified. Irregularity of the intestines may be remarked; but it is not so characterised as to force itself upon the attention. The belly during distemper mostly appears tucked up and small; the intestines, even when costiveness exists, are seldom loaded, but all except the rectum may feel empty. The animal is always bound when the bowels are acutely attacked. The first indication we get of this is often colic. The cries are high and yet full at first; but they only occur at periods, between which the dog seems easy and inclined to sleep; gradually the exclamations become more sharp and short, a quantity of dark-coloured fæces are voided, and relief is for a time experienced; the cries, however, return and become continuous; diarrhœa sets in; the excretions become more and more liquid, by degrees mixed with blood, and of a lighter color. Whenever they are discharged, pain is expressed; but as the animal sinks the cries grow less frequent, till at last the excrements pass involuntarily, and death soon takes place.
The cries, however, are not heard in every instance even of this kind, and the abdomen is not generally sensitive to pressure. When the belly is handled, the dog, by contracting the muscles covering the parts, may denote some small degree of resistance; but I have never known it to struggle during the operation. The curving of the spine, the occasional looks towards the seat of agony, and the efforts made to press or draw the belly upon the ground, will indicate the inflammatory character and the locality of the disease. The pulse does not materially aid the judgment; it becomes quicker and more sharp, but hardly to such an extent that dependence can be placed on its indications. The discharges often cease when the disease, in an acute form, becomes concentrated upon the contents of the abdomen; but the nose is almost always hot and harsh, though in a few cases I have known the part remain cold and moist even to the last. As the close draws near, a very peculiar smell, not absolutely powerful, but more sickly than offensive, is emitted. This odor is consequent upon the fæces, and when it is detected the animal seldom or never survives.
The brain, both Blaine and Youatt speak of as subject to inflammation during the latter stage of distemper. As diseases are peculiarly liable to change, and the appearances assumed at different times are by no means uniform, I may not say those estimable writers never beheld it in such a state; but I am certain I have never seen it in a similar condition; I have found it congested, but far oftener have I discovered it perfectly healthy. One of its coverings (the dura mater) has exhibited a few spots of congestion, but these have been small, each not larger than the head of a moderate sized pin, and in number about ten or twelve; generally they are situated towards the anterior of the cranium (on either side or falx), and near to the crista galli.
The bones forming the roof of the skull have, however, been highly vascular—loaded with dark blood—so that if dried they become of almost a black hue; and without disputing the accuracy of either of the authorities I have mentioned, these appearances to my mind account more satisfactorily for symptoms which no one asserts ever border upon phrenitis. The brain seems to me to be only sympathetically affected, not absolutely involved in this disease. When this is threatened, there is generally some notice given before the fits, succeeded by stupor, are displayed. The eye will sometimes brighten, and the discharge from the nose will cease. This, however, is by no means constant; as it is not rare for both to continue, or even to become more copious; but if one only should remain, the nose is certain to be the part whence the deflexion will issue. No positive dependence, therefore, can be placed upon the discharges from the eye or nose. The eye, nevertheless, is certain to denote that which is on the eve of happening. The pupil may be small; and when it is so, its decrease of size will be marked, and it will have little disposition to enlarge. This, however, is rarely witnessed. Generally the pupil is much enlarged, so much as to conceal the iris, and alter the character of the organ. The eye is moreover retracted, and the dog has a very peculiar expression of mingled pain and stupidity. If the hand be placed upon the head, it will be sensibly hot. No matter how thick the coat may be, the heat will be apparent, and the carotid arteries will sensibly throb. The coat feels dry and is warm, although the animal may be trembling to such a degree as prevents the pulse being counted. Yet the dog seems lively; it is active now, though perhaps a little while ago it was dull; every trivial circumstance now attracts its notice. The appetite is generally ravenous. The dog which only the day before was disinclined to feed, is suddenly disposed to eat more than it ever was known to consume; and it will gnaw and swallow the hardest wood for want of better provender. The amended appetite is mostly one of the symptoms, but it is not invariably witnessed; for occasionally increased activity, and the strange appearance of the eye, are all that indicate the approach of fits. It will not be long, however, before something shall be added which is more definite in its meaning. The dog which was running about suddenly stands still, and begins to smack its lips and champ its jaw. It keeps stationary while doing this, and continues so until a quantity of froth and thick saliva falls from the mouth, drops upon the ground, and then the action ceases. The animal looks around with a vacant stare, evidently not conscious where it is, and starts away, hitting itself perhaps against anything which may oppose its progress. If caught it struggles to get loose, and may even bite the hand which, when conscious, it would perish to defend. Almost immediately, however, it regains its faculties, and then seems quite as well as it appeared to be before the attack came on. It may continue subject to be thus seized for several days; or soon after the first attack, fits or convulsions may start up. During the champing colic may set in, which will only yield when the fits are established. The duration of the champing is not regular; it may be only for a few moments, or for several minutes. The attacks may be no more than one or two in the day, or twenty may occur in a single hour. Generally they remain about three days, but here also there is no rule. I have known them to be present for a week, and also to exist only for a few hours. In these latter cases the condition of the dog is generally not understood. It is taken out for a long walk, or it is indulged with a hearty meal; and in the middle of the one, or shortly after the other, it begins to champ, utters a loud sharp cry, which is suddenly cut short as if the animal was choked. The eyes glare, the mouth is open, and before perfect insensibility ensues, the dog bites at every object near it, then falls down convulsed, the limbs stiffen, the head is drawn back or twisted to one side, the urine and dung are voided; and a slate of unconsciousness, which may cease in a few minutes, or continue for hours, during which the body is in contortions, and the saliva flows freely from the mouth, stretches the poor brute upon the earth. When this is over, the dog recovers as from a trance, being always disposed to ramble, and should its strength permit, will start away at its utmost speed. There is neither to the number nor duration of these fits any limit; they may be few or frequent, and long or short. The second may end the life; or every five minutes, nay oftener, they may occur, and the animal survive for days. Any excitement will bring them on, and the passage of the fæces invariably is accompanied by an attack. Diarrhœa always begins when they commence, and the dog soon loses strength, and lies upon its side unconscious and incapable of motion; the pulse is not to be felt, and gradually without a struggle it expires. Let no man, however, be hasty in saying positively when death has taken place. Often has the life seemed gone, for the heart has been still; but minutes afterwards the animal has gasped, and then began to breathe once more. Death, however, comes at last, for if the dog sinks to such a state, I have never known it to revive.
A pustular eruption is often witnessed during the existence of distemper, and I have not seen the same phenomenon distinct from the disease. The two appear to be united, and yet we do not know the manner in which they are connected. The other symptoms are not mitigated when the pustules are matured, nor does their appearance denote any particular crisis or stage of the disorder. I have, however, most frequently seen them towards the latter or confirmed stages of distemper, and often they have immediately preceded the fits. The first indication given is a little redness, which is strictly local or confined to a particular spot. This place is not very red, but, nevertheless, it is obviously inflamed and tender; there is not much swelling, but a slight hardness can be detected. A day or two afterwards the redness dies away, and a globular eminence, perfectly round, and generally about the size of a split pea, is beheld. If it be opened, a proportionate quantity of thick pus of a healthy character escapes, and a comparatively large incrustation forms over the part; if not opened, the pustule bursts and the scab follows, but larger than in the previous case. Mostly the eruption appears on the belly and inside of the thighs, but it is seldom strictly confined to those parts. Often it affects the trunk and tail, but does not usually attack the head and fore-limbs. There is no proof that any benefit attends its development, or any known reason for attributing it to any cause; save only such as can be drawn from the statement, that I have commonly observed it in pups of a weakly constitution and emaciated condition.
The disposition to eat or gnaw some part of the body is often shown to an alarming degree, but is seldom exhibited save in the latter stage of the disease. The dog is observed to lick one of its paws, or mumble at its tail, for some days. The part is always one of the extremities, and is evidently tormented with a violent itching which cannot be allayed. The animal at length, irritated by the torture, attacks the member with its teeth. The skin is first removed, and then the flesh. The mouth may be covered with blood, the teeth clogged with hair, and the very bones attacked; but the pain which the sight of the mangled surface suggests to the spectator seems not to be felt by the dog, which appears desirous only of destroying its own body. I have known two of the toes of one fore-paw to be thus consumed, so that amputation was afterward imperative, portions of the metacarpal bones being laid bare. In several instances the root of the tail has been eaten, until the sacrum and first tail bones, with the nerves, were exposed. The rage cannot be overcome, and, unless the disposition be prevented by mechanical means, the consequence will be fatal. No author that I am acquainted with has noticed this peculiarity; and in general it is attributed to other causes than distemper, which is either not observed, or is supposed to have been got over.
Tumors on various parts of the body, and of different kinds, sometimes but not usually accompany the disease; but as I have not been able to satisfy myself they are peculiar to the disorder, or induced by any other cause than the debility attendant on distemper, there is in this place no occasion to more than point out the possibility of their appearance. They are unfavorable as indications of general weakness, but they do not seem to possess any further or direct influence over the course of the affection.
The genital organs rarely escape altogether. A thick purulent discharge, or one of a glairy nature, is often present in the male throughout the attack, and nearly always during recovery. In both sexes the bladder in the latter stages is apt to be paralysed, and the accumulation of the urine then becomes a prominent symptom. The recovery often commences after relief has been obtained, but if the necessity be overlooked, death generally ensues.
Paralysis of the hind extremities is occasionally witnessed, and when seen is generally sudden in its appearance. Sometimes, however, the loss of power is gradual, and when such is the case the hopes of a cure are always diminished. If the power of motion be lost suddenly, costiveness mostly exists; and if, on the other hand, it should be gradual, there may be diarrhœa, which will terminate in death.
Twitches, choræa, or Saint Vitus's dance, are not very usual, and may continue for months after every other symptom has subsided. All four limbs are sometimes violently agitated, and even during sleep are not quiescent. The motion is incessant, and when this is the case the animal dies, worn out by the want of bodily rest. In the majority of instances only one limb is affected; and a species of independence of volition, or incapability of controlling its movements, accompanies the affection. Though never still, the leg is comparatively useless, and is carried in a manner which denotes this fact. The muscles of the trunk are less commonly attacked, but they do not always escape. When the legs have not been thus affected, I have known the abdominal and thoracic muscles to be troubled by continuous twitchings; which, however, have been for the most part slight, and have subsided more quickly than have those of the extremities, when they have been diseased. Cholera comes on gradually; its commencement is hardly to be perceived, and it is seldom observed before the distemper is fully developed—even sometimes only when the disorder appears to be subsiding. It is not rare for it to start up while the animal is apparently recovering; and when it does so, it is always most difficult to remove. No pain is felt in the affected limb; the part rather seems to lose some portion of its sensibility.
When the hind parts are paralysed, feeling may be entirely gone; so that a pin thrust into the flesh of those parts does not even attract the notice of the dog. This does not occur in choræa, but the consciousness is dulled by that affection. The convulsed limb may be more roughly handled than the healthy ones; but violence will excite those answers which truly indicate that insensibility is not established in it. If nothing be done for the twitchings, the limb will waste; at last the general system will be sympathetically involved, and the body will grow thin. This, however, may not happen until long after all signs of distemper have disappeared; for choræa, though well known to be often fatal, is always slow in its progress, and never attended with immediate danger.
Such is an outline of the leading symptoms; and it now remains only to more particularly point out those which indicate death and denote recovery. The third or fourth week is the time when the dog mostly dies, if the disorder terminates fatally; and six weeks is the average continuance of the attack. Rapid loss of flesh is always a bad sign, and it is worse in proportion as the appetite is good, because then nature has lost the power of appropriation. The presence of vermin is likewise a circumstance which in some measure is deserving of notice. If a dog becomes, during the existence of this disorder, unusually infested with fleas, or more especially if lice all at once cover its coat,—as these parasites ever abound where the body is debilitated and the system unhealthy,—they are at such a period particularly ominous. The coat cannot, while the disease prevails, be expected to look sleek; but when it becomes more than usually harsh, and is decidedly foul, having a peculiar smell, which is communicated to the hand when it is passed over the body, the anticipations are not bright. The most marked indication is, however, given by the tongue. When this is only a little whiter than it was in health, we may hope for recovery; but if it becomes coated, discolored, and red and dry at its tip and edges, the worst may be foretold. The warning is the more decided if the breath be hot and tainted, and the belly and feet cold to the touch. While the dog can stand and walk, however feebly, there is no reason to despair; but when it falls down, and lies upon its side, rarely is medicine of much avail. Even then, however, it will sometimes recover; but if, while in this state, injections are returned as soon as they are administered, the chance that it can survive is indeed remote.
Recovery, in extreme cases, usually commences after diarrhœa which had set in has subsided, rather than during its attack. This is the only semblance to anything approaching a crisis which has come hither under my observation. If simultaneously the eyes lose their red and glassy aspect, and the cough returns, the danger may be supposed to have been passed. For weeks, however, the animal will require attention; for the convalescence is often more difficult to master than the disease itself is to cure; and relapses, always more dangerous than the original attack, are by no means unusual. The recovery may not be perfect before one or even two months have expired; but usually it is rapid, and the health is better than it was previous to the disease. A dog which would before never make flesh, having had the distemper, will often become fat. I once tried all in my power to relieve a Newfoundland dog of worms, but though I persisted for months, I was at last reluctantly obliged to admit the case was beyond any treatment I dared employ. A fortnight after I had given it up, the same animal was brought to me, suffering under evident distemper. I was not displeased to see it in that state, for I felt I could overcome the disease; and I told the proprietor that with the distemper the worms would depart. So it proved, and the dog has not since been subject to the annoyance.
When the violence of the disorder has declined, the skin generally peels, the cuticle is cut off, and the hair is scurfy. I have even known the soles of the feet to cast their outer covering, and in one case three of the nails were shed. The teeth, also, are coated with a thick fur, and the breath is offensive; but as the strength returns at the same time, these circumstances are not to be viewed in a serious light. In one or two instances, where the system seemed to be so shaken that it retained no strength to cast off the lingering remnant of the distemper, mange has burst forth, and proceeded very rapidly; but it yielded with equal speed to mild external remedies, and is therefore only to be feared inasmuch as it disfigures the dog for a time, retarding the ultimate restoration to health by further taxing the enfeebled body.
During the recovery from distemper, small and delicate animals—terriers and spaniels—are very liable to faint; the dog is lively, perhaps excited, when suddenly it falls upon its side, and all its limbs stiffen. A series of these attacks may follow one another, though generally one only occurs; when numerous and rapid, there is some danger, but, as a general rule, little apprehension need be entertained. The fainting fits are of some consequence, if they exist during a sickening for, or maturing of, distemper. In pups that have not passed the climax of the disease, they are not unseldom the cause of death; but, even in that case, I have never been convinced that the measures adopted for the relief did not kill quite as much or even more than the affection. When the symptom is mistaken, and wrong remedies are resorted to, the fainting fit will often continue for hours, or never be overcome. When let alone, the attack mostly does not last longer than a quarter of an hour, and under judicious treatment the consciousness almost immediately returns. When the fainting fits occur during the progress or advance of the disease—that is, before the symptoms have begun to amend—it is usually preceded by signs of aggravation. For twelve or twenty-four hours previously the dog is perceptibly worse; it may moan or cry, and yet no organ seems to be decidedly affected more seriously than it was before. I attribute the sounds made to headache; and, confirming this opinion, there is always some heat at the scalp. The animal is dull, but immediately before the collapse it attempts to wander, and has begun to move, probably panting at the same time, when it falls without a cry, and stiffens. In this state—the rigidity occasionally being less, but the unconsciousness continuing unchanged—it will remain; the eyes are turned upward or into the skull, the gums and tongue are pallid, the legs and belly cold: the appearances are those of approaching death, which, unless relief is afforded, may in a short time take place. When the fainting occurs after convalescence is established, the attack is sudden, the symptoms are less violent, and the coma of shorter duration. In this last case there is generally little danger, but there is always sufficient reason for alarm, and help ought never to be delayed. These attacks are commonly confounded with true distemper fits, from which they are altogether distinct; and from which they may be readily distinguished by the absence of the champing of the jaw, the want of any disposition to bite, the immediate insensibility which ensues, the shrieks not being heard, and the urine or fæces not being voided. Nevertheless, the two are usually confounded, and hence many persons are found asserting that distemper fits are easily cured; and several dogs have been shown to me at different times, which their owners were confident had been attacked by distemper fits, and radically cured by the most simple, and often ridiculous specifics. I have sometimes in despair—even against my reason—tried these boasted remedies, but in no instance has the result rewarded me. Where there was real occasion for a potent medicine, and little hope that any drug could benefit, the nostrums have, without a single exception, belied the confident recommendations with which they were offered, and either have done harm or proved inoperative.
The symptoms of distemper, as the reader will, after wading through the foregoing description, have perceived, are numerous and complicated; they admit of no positive arrangement, being both eccentric in their order and appearances. Redness of the eyes, with discharge from both eyes and nose, accompanied with ordinary signs of illness, are the early indications; but even these are not to be sought for, or to be expected in any single form. The judgment must be exercised, and study strengthened by experience will alone enable any man to pronounce the presence of distemper in many cases; while, perhaps, without knowledge or practice any person may recognise it in the generality of instances.
The treatment is rendered the more difficult because of the insidious nature of the disorder, and the uncertain character of its symptoms; under such circumstances, it is no easy task to make perfectly clear those instructions I am about to give. I am in possession of no specific; I do not pretend to teach how to conjure; I am going only to lay down certain rules which, if judiciously applied, will tend to take from this disease that fatal reputation which it has hitherto acquired. I shall be obliged, however, to leave much to the discretion of the reader; for it would employ too great a space, did I attempt to make provision for all possible accidents and probable combinations.
The diet is of all importance; it must be strictly attended to. In the first place, meat or flesh must be withheld. Boiled rice, with a little broth from which the fat has been removed, may be the food of a weakly animal, but for the majority bread and milk will be sufficient; whichever is employed must be given perfectly cold. Sugar, butter, sweet biscuits, meat, gravy, greens, tea or pot liquor—either luxuries or trash—must be scrupulously denied in any quantity, however small. Skim-milk, if perfectly sweet, is to be preferred, and coarse bread or ship biscuits are better than the same articles of a finer quality. These will form the diet, when the dog can be brought to accept them; and to rice, the favorite—however great may be the pity he elicits, or however urgent may be his solicitations for a more liberal fare—must be rigidly confined. If, after a few trials, the dog stubbornly refuses such provender, meat must of necessity be given, but it should be of the very best description, and rather underdone. Of this kind, it ought to be minced, and mixed with so much rice or ship biscuit as the animal can at first be made to eat with it; the rice or biscuit may then be gradually increased; and in the end the vegetable substance will constitute, at all events, the major part of the support. Water, constantly changed—a circumstance too little attended to where dogs are concerned—must be the only drink; the bed must be warm and dry, but airy. Cleanliness cannot be carried to too nice an extent; here the most fastidious attention is not out of place. Let the kennel be daily cleared, and the bed regularly changed at least thrice-a-week; straw or hay is better for the dog to sleep upon than cushions or blankets, which, being more expensive, are not so frequently replaced. Too much hay or straw cannot be allowed, but, on the other hand, it is difficult to regulate the quantity of the finer articles. In the last kind of bed the animal is often almost smothered, or else he scrapes them into a lump, and lies shivering on the top; whereas, when he has straw to lie upon, he can either creep beneath it, and shelter himself when sensible of cold, or expose himself to the air when oppressed by the fever. The sensations being the only guide, it is best to leave the dog, as much as possible, capable of obeying its instinct; but always let the bed be ample, as during the night the shivering generally prevails, and the cold fit is entirely independent of the heat to be felt at the skin, or the temperature of the season. Let the dog be kept away from the fire, for, if permitted, it will creep to the hearth, and may be injured by the falling cinders, when the burn will not perhaps readily heal. A cold or rather cool place is to be selected—one protected from wet, free from damp, and not exposed to wind or draughts. The kennel, if properly constructed, is the better house, for dogs do best in the open air; the only objection to which is, the chance it offers of the animal being drenched with rain. If the kennel can be placed under an open outhouse, I should always have it put there; and what else I would recommend is, of course, told by the line of conduct which I pursue.
