Why are my dog's nipples and vulva still swollen 6 months after spay?

Updated On September 23rd, 2025

My dog was spayed 6 months ago. However, her nipples and vulva are still swollen. She was cared for correctly after her spay as it was completed during her one week stay at the vet while we were on vacation.

I suggest you take her back to the vet for an exam. She may have a piece of ovary that was left behind during surgery that is causing stimulation of the mammary and vulvar tissues. The vet can do some hormone blood testing, a vaginal cytology and/or an abdominal ultrasound to check for this. ( https://vcahospitals.com/know-your-pet/ovarian-remnant-syndrome-in-dogs )
