The sudden ability of a dog to express milk may be due to pregnancy. Usually after the dog is 50 days pregnant, the mammary glands may develop and secrete some milk. Secondly, some dogs that have not been neutered may also have this abnormal secretion of milk due to endocrine disorders, leading to pseudopregnancy. Since the symptoms of pseudopregnancy are similar to those of pregnancy, it is generally difficult to distinguish. Therefore, if you want to confirm the diagnosis, you should take the dog to the pet hospital for examination. Especially if the dog expresses milk without being bred to become pregnant, the owner must attract attention.

1. Pregnancy

If the dog is pregnant, the breasts will swell and secrete milk during pregnancy. In this regard, owners need to pay attention to observe whether the dog has been bred before, or has mated with other dogs. If you notice breast development and erect nipples a few days after mating, it is suspected that your dog is pregnant. If conditions permit, it is recommended to go to a pet hospital for an X-ray and B-ultrasound examination to determine whether the dog is pregnant.

2. False pregnancy

Endocrine disorders in dogs can lead to pseudopregnancy, and the breasts can also secrete milk. Usually, dogs with pseudopregnancy will have reactions such as increased appetite, vomiting, and diarrhea in the early stage, and then they will have an enlarged abdomen, enlarged mammary glands, and secretions. If it is a false pregnancy caused by endocrine disorders, the symptoms will generally disappear after 1-2 weeks.
