Could my unspayed dog's swollen nipples and discharge be false pregnancy?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Female | unspayed | 10 months and 14 days old | 5 lbs

I have a 10 month old peagle. She got her first period 2 months ago. Recently her nipples swelled and she vomited occasionally. Today I noticed that she has nipple discharge. She was in contact with a male dog but they never mated. Could this be a false pregnancy? If so what should I do?

Hello. If this is a false pregnancy, there really is nothing much you can do at home. Unless you are going to use her for breeding, spaying will prevent this from happening again, but if you do not want to spay her, this will not cause any loss in fertility if you decide to breed her in the future. If her symptoms are mild, it is best not to do anything at all, as any stimulation of the nipples by applying warm compresses or wrapping them to prevent milk leakage will just stimulate more swelling & milk production. If she is licking herself, you may need to put a cone or E collar on her. If she really seems to be uncomfortable or there is a lot of leakage, sometimes we will treat these dogs with diuretics or even hormones. So, see how she does & see your vet if the situation worsens.
