I had my sister call me about an abondoned chocolate lab puppy. It has something on its head. Right now it is about inch long and about half an inch wide. It is white, flaky no hair on it. The vet my sister grooms dogs for said it is a wart and put fungal cream on it. I took her to my vet and he had no idea what is was but said do not put anything on it. It may go away. Has anyone encountered this before. I feel so bad for the puppy she is probably only about 8 weeks and a little old lady found her walking along side a busy highway in the middle of nowhere. Needless to say i hope i never find the person who left her on the highway to get run over.
