Momo has a white bump, kinda like a white head on his lower back. Vet knew right away that it wasn't a tumor, he said dogs get them, like warts. Could it be that? Vet said they can spread & he can nuke it w/dry ice thingy (can't remember the term he used!) & scoop it out.
He said if he didn't get the roots out, it will probably grow back...& it did. Now it's 2 little bumps clumped together, I'm just leaving it, it hasn't spread anywhere else on his body so I'm not too concerned. But I am watching to see if it gets any bigger, than we might need to biopsy it again.
Hope it's nothing serious, the vet can take a look @ it & will be able to tell you what it can be. Oh & don't google!
