Do dogs get pregnant when they are still bleeding or just after?

Dogs can get pregnant while they are still bleeding, during estrus, or just after bleeding, during diestrus. The timing of ovulation can vary between individual dogs and also between different estrous cycles for the same dog. Ovulation typically occurs anywhere from 10 to 14 days after the onset of bleeding, but it can occur earlier or later in some cases.

Generally, the best time to breed a female dog in order to maximize the chances of conception is during the latter half of estrus, closer to ovulation. This period is often referred to as the fertile window. However, it's always recommended to seek advice from a veterinarian or an experienced breeder who can help determine the optimal time for breeding based on the individual dog's estrous cycle patterns.
