My Dog, Buttons is a 12 year old Sheltie. She is is in good health with no ailments. Recently we discovered a small tumor like projection from her right leg, it is pink and about the size of a penny. Upon going to the local Farm Vet we learned that it is a "hemangioma" of some sort. He gave her prednisone to see if it would shrink it down. She has now taken the last of her prednisone and it has not shrunk but has not gotten larger, but has a small hole in the side of it. I am attaching a picture of it, for advice as to what you all may think this could be and what I can do for her. I cleaned it with peroxide and put Triple Antibiotic Ointment on it. Any advice or comments are appreciated. Thanks and May God fill your lives with Blessings!
