Why is my spayed dog having bloody mucus vaginal discharge?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 50 lbs

My 10 year old labradoodle has had bloody, mucus-y discharge coming out of her vaginal area before she has a bowel movement about once per day for the last 3 days. Her energy and appetite seem normal, she's drinking water, and seems fairly normal other than that. The vet saw her, tested her urine, and ruled out a UTI, and said some sort of infection is possible. She has chronic digestive issues so he didn't want to put her on antibiotics unless this discharge continues. What could be the cause?

Dogs can get a vaginitis or a stump pyometra. Generally a dog with a stump pyometra will act sick so this seems less likely at this time. I recommend to keep your veterinarian updated. If the discharge continues beyond another 3 days, antibiotics may be indicated. probiotics may help to maintain a better bacterial flora in Ella's vagina and keeping the hair trimmed short around the vulva will also help. Wiping her after she uses the bathroom with a pet wipe may also help (make sure not to wipe from the rectal area down). I hope this helps and please feel free to post any additional questions.
