Since ovulation takes place a day or two after the bitch will first accept a male, it seems likely that a breeding program will be highly effective if we breed a bitch as soon as she will receive a male, then repeat the breeding two days later. Generally, conception is more likely following the earliest possible normal breeding.

Conception success depends on a bitch’s attitude, her general health, and how well her hormones are working. Most of us who have kept intact females can attest to the fact that when “turned out,” most bitches do quite well on their own. Nature’s timing seems to be highly effective.

Whereas males are usually indiscriminate in their choice of mates, many times females will select their partners with discretion, allowing only a particular male or two the privilege of mating with her. Unfortunately, they do not always make the most prudent choices when left to their own devices.

Puppies of a single litter may be sired by more than one male. That usually occurs if the bitch is allowed to cruise the streets to choose her own mate(s), and is bred by several males during her receptive period (a practice to be discouraged at all costs).
