Reproduction
In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females,[3][52] although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles semiannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation.[3] Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male.[3]
2–5 days after conception fertilization occurs, 14–16 days later the embryo attaches to the uterus and after 22–23 days the heart beat is detectable.[53][54]
Dogs bear their litters roughly 58 to 68 days after fertilization,[3][55] with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies,[56] though this number may vary widely based on the breed of dog. In general, toy dogs produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.
Some dog breeds have acquired traits through selective breeding that interfere with reproduction. Male French Bulldogs, for instance, are incapable of mounting the female. For many dogs of this breed, the female must be artificially inseminated in order to reproduce
