My dog has an anal gland tumor. What are the best treatment options?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 13 years and 3 months old | 10 lbs

My dog has been diagnosed with having a tumour near to an anal gland that has also been treated successfully for an ulcer on the anal gland that was successfully drained and all infection has been removed. However, now a "mass" has been discovered in that same area and I would like to know what my best options for treatment of the tumour would be for him. He has had a needle biopsy that was sent off to the lab. so we know that the swelling , as it was first called, is definitely a tumour.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Unfortunately, tumors of the anal gland tend to be quite aggressive. The best option is to discuss the case with an oncologist. Surgery and/or radiation therapy with some chemotherapy as well is the treatment a human would get, and is available for dogs in some areas. The best treatment depends on exactly what type of cancer it is. Once the results are in, I would recommend having a consult with an oncologist to discuss the options and outcomes, as you might be surprised at the options. Often a CT will be recommended as well to check for any spread of the cancer prior to starting chemo/radiation/surgery. Best of luck with Jockey.
