Hi, my 12 year old Rottweiler the last few months has started to form large buble type objects around his anus. they don't seem to cause him pain but they concern me. Any idea what these could be?

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! These look classic for perianal gland tumors. This is very common in intact dogs. The majority of these tumors are benign though a small percentage of them are malignant. I recommend you take him to your veterinarian for a test called a fine needle aspirate which can help distinguish these tumors from other more concerning tumors. If it truly is a perianal gland tumor, most of the time they resolve or greatly improved by neutering the dog as they are driven by hormones. If they are not bothering him, this may be enough. In cases when they are starting to bother the dog, you can also consider removal. Feel free to request a consult with me if wanting more information on the next steps. Good luck with your pup!
