Hi, thanks for using Petco Pet Education Center, formerly Petcoach!
In true pregnancy there are puppies present in the uterus (womb). Hormones that keep the pregnancy going are produced by the corpus luteum and from the placentas.
The exact cause of a false pregnancy is unknown. However, hormonal imbalances, especially of progesterone and prolactin, are thought to play an important role in its development. Symptoms start 1-2 months after the heat cycle ends. There are no puppies present. Some female dogs have been found to show such abnormal symptoms within 3-5 days after being spayed
I hope this helps!

Thank you for submitting your question regarding Kali. False pregnancies occur in dogs that have not been spayed. The hormonal fluctuations make the dog feel, act and look pregnant despite not being. The dog's belly and mammary glands can enlarge. She will display nesting behavior and may find household objects to tend to like puppies. The false pregnancy can recur with subsequent heat cycles until she is spayed. I hope this information helps!
