Why do mothers mate with dogs?

1, the bitch will send messages to the surrounding dogs during estrus.

Bitches will emit a special pheromone during estrus, and the surrounding male dogs will perceive this pheromone through their sense of smell. If the son of a bitch is also an adult male dog, then she can also feel the existence of this pheromone. This may cause it to have some strange reactions to its mother's behavior, such as courtship, chasing or flirting.

2. Bitches will show interest in the surrounding male dogs during estrus.

Bitches show interest in male dogs around them during estrus. This interest may be manifested in being very friendly to the surrounding male dogs, approaching them, twisting their bodies and even rubbing them. If the son of a bitch is also an adult and is around, then he may also be one of the targets of the bitch's behavior.

3. Incomplete reproductive isolation

The breeding isolation of dogs is not as strict as that of wild animals. In the family environment, sometimes a bitch meets her son or fraternity by chance, which may lead to their mating. This is one of the main reasons for this abnormal phenomenon in the family environment.

4. Lack of mating barriers between bitch and son.

In wild animals, because it is particularly important to avoid the genetic diversity of populations by avoiding inbreeding, mating obstacles, such as physical, social or psychological obstacles, usually occur. However, in the family environment, because the bitch and her son or brother have been living together, the social and psychological relationship between them will make them lack these mating obstacles, thus increasing the possibility of such abnormal events.
