My Boxer has a watery, painless swelling on his rear. What's wrong?

It may be a mass or tumor. Infection or trauma cannot be ruled out. You would need to have Creed physically examined by your veterinarian to diagnose the lump. A fine needle aspirate can be done to collect samples for pathology. This may provide a diagnosis. Once results are returned, you can discuss treatment options with your veterinarian. If Creed is licking or chewing at the area, place an e-collar (cone) on him until the issue is resolved.

Boxers are very prone to skin and other forms of cancer. While this looks well defined I recommend a veterinary exam and possibly a biopsy to see if it’s cancer. They can remove the bump and check her eyes and the other skin mass at the same time. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Diamond.

Hello If possible a photograph of this lump would be helpful. It could be a lipoma (a harmless fatty tumor) but Boxers are known for developing mast cell tumors on their skin. Those types of tumors need to be removed as they can cause issues with the GI tract and even anaphylactic reactions.

Oh goodness! Poor Jack! As a veterinarian and fellow boxer owner I would expect that this is likely an allergic reaction to an insect sting or spider bite. Boxers are very reactive! They often have gastrointestinal signs with these reactions and usually take a few days to return to normal where as most dogs will respond within hours. He needs to be seen by a veterinarian immediately for some steroids and possibly even epinephrine. If his face is that swollen I worry that his throat could be swollen too, which could be very serious if it gets worse. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

I am so sorry to hear that Boxer has this concerning mass. Because you have noticed the mass over a period of a few months and because it is bleeding repeatedly I would have it seen by a veterinarian. There are many possible causes for masses in a dogs skin including foreign bodies, bacterial infections, cysts, and several types of benign and well as malignant tumours. In the meantime, place an e-collar, or cone, on Boxer to prevent him from biting or scraping the mass. This will hopefully stop him from bursting it again, as well as stop him from possibly infecting the area. Measure the mass with a ruler so you can compare its growth in a couple weeks time. Rapidly growing masses are more concerning. I hope that this answer was helpful and more importantly that Boxer feels better soon. Warmest regards to you both.

I would have Abby seen by a vet for this bulge which could be a mass. Unfortunately in senior dogs, there is always a chance a mass could be malignant. It could be compressing her intestines and colon leading to small amounts of poop being passed. Any suspicious masses should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the mass to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Abby seen by a vet first thing on Monday to have this mass examined and diagnosed so it can be treated.

Thank you for submitting your question regarding your dog. I do recommend having him evaluated. He may have a ulcer or wound there, but there is more serious disease known as a perianal fistula. You will want him to receive treatment and ensure this is not the case. In the meantime, place an E-collar on him if he is trying to lick the area. I hope this information helps!
