My female dog is making milk but isn't pregnant. Should I worry?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 5 years and 10 months old | 5 lbs

My female chihuahua, Cosita has been drinking her own milk. She has never had a litter before and is the only dog in the house so I know she couldn’t get pregnant. Can someone tell me the reason for this? And how she is making milk if she’s not pregnant? I’m worried!

Cosita could be experiencing a false pregnancy, which would cause her to produce milk and show symptoms of being pregnant without actually being pregnant. These symptoms will go away, as there is no treatment for a false pregnancy, but I would recommend having her spayed. That's the only way to keep her from having another false pregnancy, and it will keep her from developing a pyometra later on in life. A pyometra is a life threatening infection of the uterus that is fatal without treatment. It makes a dog extremely sick, and the recommended treatment is spaying. Spaying a dog with a pyometra can cost into the thousands, while simply spaying her now will only be hundreds. For these reasons, I would make an appointment with your vet to have her spayed. I hope this helps!
