What should I do if my dog has a painful nipple lump?

Updated On September 23rd, 2025

Pet's info: Dog | American Staffordshire Terrier | Female

I recently rescued an American Staffordshire Terrier who has, what appears to be, an abcess growing from her nipple. I can tell it is painful and I'm hoping to find causes and treatment procedures so that I can get this beauty back to a perfect bill of health.

Oh no, poor Pebbles! It's certainly possible she has an abscess, but if she is intact (not spayed), then it could be a mammary tumor. Poor girl that it's painful! Because it's painful, it's best that she is seen by a vet first thing in the morning. The vet can diagnose what is causing this lump, and then can discuss treatment otiose with you. If it is an abscess, it will need to be drained and flushed sterilely, and she will need antibiotics for the infection. Should it be a mammary tumor, then there's a 50% chance it's malignant. Depending on if it has spread or not, removing it surgically may be curative.

    Pebbles may have a mammary gland abscess, a cyst or a mammary tumor. An abscess would need to be lanced and flushed by a veterinarian and one needs to make sure that it did not penetrate the abdominal wall to the abdominal cavity. If it is a tumor (your vet can easily distinguish between the two), it will likely have to be removed surgically. So there really is nothing you can do at home other than take her to the vet for an exam and relevant treatment according to the findings. In case of an abscess your vet will also want to prescribe antibiotics and pain medicine.
