Dog's vagina & mammary glands inflamed after heat. Is she pregnant?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 1 year old | 20 lbs

Lila is a year old, she already had one heat which finished two months ago and she is starting to have her vagina and mamary glands inflamed. Is this normal? Is possible to spay her still? Would it cost a lot? What if I don't do it?

This would be quite soon for Lila to go into heat again, and I'm wondering if she possibly had contact with an intact male dog during her first heat. Her symptoms could be indicative of a pregnancy, but it could also be due to a false pregnancy. This is when a dog shows signs of being pregnant without actually being pregnant. I would have her seen by a vet tomorrow, who can confirm if she is pregnant or is experiencing a false pregnancy. As for spaying, should she be pregnant, she would be far along in her pregnancy that at this point, spaying may not be an option. If she is having a false pregnancy, yes she can be spayed but keep in mind that if there is an increased blood flow to her uterus, the surgery will cost a little more due to the increased risks. You can speak to your vet to find out the costs involved. I would recommend having her spayed if you can, however, as it will reduce her chance of developing mammary tumors later in life (she will have an 8% chance of developing them), and will eliminate the risk of developing a pyometra, which is a life threatening infection of the uterus. Take her into your vet tomorrow for an exam and a discussion. Good luck, I hope this helps!
