A couple days ago we noticed a crusty round mass the size of a quarter on his inner rear right hind leg, on the inside of his ankle bone. We are concerned and are not sure exactly what it could be. We do have a Vet appointment Monday night for his second set of shots. He is 12 weeks old. It does not hurt him when we touch or squeeze the area. We are worried and are looking for any feedback of the possibilities. Below I included 2 pics of his bump. Thanks.....
