Hello, I'm Dr Gary. I've been practicing veterinary medicine since 2007. I look forward to helping with your questions/ concerns.

Expert:  Dr. Gary replied 1 year ago.

The main concern I would have with the lump on the tail is a mast cell tumor. These are common skin tumors that boxers will frequently get. If this is a mast cell tumor, rapid detection and surgical removal is key for a good outcome. If they are diagnosed and removed completely before they spread, it can be cured. If they spread to lymph nodes or grow too large, then the prognosis worsens.

If this is not a mast cell tumor and it's some other benign mass, it can be ignored as long as it's not causing any signs.

The acting strange and vomiting is not likely related to the tail lump. I don't have a good reason for that. If they do remove the mass, they'll likely run pre-anesthetic bloodwork to make sure there is no evidence of underlying kidney or liver disease. If you want to give something over the counter for nausea, you can use Pepcid (Famotidine)- 20 mg every 12-24 hours as needed.

I hope this helps, let me know if you have any other questions.

Sorry, I was helping another client.

The lump is most likely some type of tumor. Tumor doesn't always mean something bad. It could be a benign tumor that you ignore or it could be an infectious tumor (abscess). But, it could also be a mast cell tumor or some other bad kind that you really want to know about as soon as possible.

There are many things it could be. Step one is getting a needle aspirate and looking at the cells to see what it is.
