I have a two year old golden retriever and I noticed he was biting and licking his paw on the bottom. I took him to the vet and they did not know what it was but referred me to a specialist. He has been acting normal besides the biting and licking of his paw. I have taken a picture of the growth on his paw and wanted to ask if anyone has seen anything like this. It is towards the bottom left side on his paw pad shown in the picture. I am seeing a specialist near the end of September to get him checked out. Thanks for the opinions!
