Skin disease progresses and signs can change with time, so knowing the age at onset of symptoms and the initial clinical presentation is valuable. For instance, signs of food allergy can be seen in puppies less than 4 months of age. If a 3‐year‐old dog with recurrent pruritus and dermatitis presents for evaluation, being aware that clinical signs have been present since the patient was 5 months of age may make a differential such as food hypersensitivity more likely in the veterinarian’s mind. Discussion of the evolution of clinical signs (e.g. initially just ear infections, now also paw licking and scooting on rear end) is also important, as owners may not recognize previous issues as significant.
