My unspayed dog's nipples are leaking. Pregnant or false pregnancy?
HI, thanks for using Petco Pet Education Center, formerly Petcoach!
Normal pregnancy length in dogs is 60-63 days. If she mated right before adoption then she could be pregnant. Puppy heart beats can be detected on ultrasound at 28 days gestation and we can see their skeletons on X-rays around 50 days. She could be pregnant or she could be suffering from a false pregnancy which occurs after they have a heat cycle from a hormonal imbalance. This imbalance causes the body to think it is pregnant when it actually isn't. The dog can develop mammary glands, produce milk, nest, carry stuffed animals around like babies, act anxious. It resolves with in 2-3 months.
I would make an appointment with your Vet to see if you can confirm or deny pregnancy.
I wish you the best!
