My baby Jinx, who is a two year old female with a petite head, has been bleeding from the corners of her mouth. Compared to our other boxer her jowls seem really bumpy and fleshy--not usually abnormally so. But last Thursday night the corners of her mouth started bleeding a bit and seem really inflamed. Vet thought maybe she got into yellow jackets or something and gave cortisone shot and prescribed benadryl. Thought she was better but tonight she is bleeding again. Anyone have any ideas?
