What's this growth on my 9-month-old Boxer puppy? Is it a wart?
Hi Kari! Unfortunately, there is no way to share photos in the forum, but you can request a consult with me where you can share photos :-)
As for the growth, in such a young puppy is it more likely to be a benign growth like a wart. Boxers are prone to mast cell tumors, so there is a potential it could be that, but it would be rare as there are mostly seen in Boxers around eight years of age. I would have Myra seen by a vet for it. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump 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.
