So do dogs have menstruation?

The belief is widespread that bitches have the rule in the same way as human dogs.The woman's cycle is repeated every month.Towards day 14 ovulation occurs and a couple of weeks later, on average on the 28th, if the egg has not been fertilized, the inside delutero, which receives the name of endometrium and that had thickened to receive the embryo, is detached causing the bleeding that we know under the name of menstruacion.

The bleeding in women corresponds to the end of the cycle.In contrast in the bitches it indicates the beginning of the fertil period.Therefore, contrary to what happens in women, it is during the bleeding, specifically in the estrus, when the dog is going to ovulate and may become pregnant.We must exercise extreme precautions during those days.
