Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 1 year and 11 months old | 164 lbs
My 2 y/o dog (mix) has a gray-colored growth on her left lower lip. It looks a bit like a barnacle--it's round, but the top part (furthest away from her lip) is open, like a barnacle. It could look like it was enclosed and burst; the edges look jagged. The closest possible match I found online is tumors formed on dogs' gums from the papilloma virus, but this looks a little different than the pictures online I found.
