A friend's dog I saw yesterday is about 16 and has an odd growth on her cheek, a bit below her eyes. It looks almost like the skin on a dime-sized patch of her face swelled up in these huge bumps. It's mostly a pinkish color, but around the edges are discolored with purplish skin. Their vet (the two times they took her there) told them point blank they didn't know what it was/ They cut it off, but it regrew eventually. Any ideas about what it is so I can see if they can find another vet to help them?
