So about five minutes after getting home from college I found a little bump on Dusty's chest near his shoulder. It's pink, has sort of yellow crusty stuff around it, and has some redder spots. My father thinks it's a wart and wants to get wart remover from CVS (I hope he's joking, and yes, of course I will take the dog to the vet). Has anyone seen anything like that? And what did you do about it?
