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 )

The loose skin may be a result of the mild swelling after her spay resolving and the hard spot could be scar tissue if it's near her incision site. It might be a good idea to have your vet check it to be safe.

There is a possibility that she was in heat when she was spayed. The swellings are caused by female hormones and it will take a week to two weeks for the hormones to leave the body and the swelling to go away.

The incision and area actually look very good. There appears to be no bruising or redness. Some post op swelling is normal but is not cause for concern. If she was in or near heat at the time of spaying, this could account for what you are seeing. Any swelling should resolve given time. Continue to medicate her as directed by your veterinarian and monitor for lethargy, bleeding, bruising or for an open incision. An e-collar (cone) is always recommended after surgery to prevent licking of the site.
