Pseudopregnancy in dogs is mainly caused by hormonal disorders in the body. Secondly, when the corpus luteum in the dog's body becomes pathological, or the dog suffers from endometritis, uterine effusion, pyometra and other diseases, false pregnancy may also occur. In addition, if your dog is fed food or growth supplements containing a large amount of estrogen, which will lead to a hormonal imbalance in the dog's body, it will also cause false pregnancy.

1. Caused by hormonal imbalance in the body

Hormone imbalance in the body is one of the most common causes of false pregnancy in dogs. False pregnancy usually occurs after the female dog goes into heat. After the dog goes into heat, the hormones in the dog's body will change. These hormones will prepare the uterus to welcome the fetus. If the dog conceives successfully, hormones will continue to be produced. If the dog does not become pregnant, hormone levels will begin to decrease after 4-6 weeks. When the amount of progesterone hormone secreted by the corpus luteum in the dog's body is equivalent to that during pregnancy, and it exists for too long, pseudopregnancy will occur.

2. Caused by reproductive diseases

When the corpus luteum in a dog's body becomes diseased, it will cause abnormal progesterone secretion. If the dog suffers from endometritis, uterine effusion, pyometra and other diseases, it will also cause abnormal secretion, thus causing pseudopregnancy in dogs.

3. Caused by diet containing a large amount of estrogen

In order to make their dogs grow quickly, some owners feed their dogs food or growth supplements containing a large amount of estrogen. This can easily disturb the hormonal balance in the dog's body and cause the dog to have a false pregnancy.
