Well both dogs are having issues with there ears. I noticed yesterday evening that Sadie's ears are really red with some very small scabs which are a result of scratching I guess. Charlie had a spot on his ear that was a scab, well Sadie licked it off and there's a big red bump there. I'm guessing Sadie has gotten ear mites, only thing I can think of with Charlie is possibly a tick bite. We give them Frontline regularly up until the first couple of frosts. Anybody got any ideas on what could look like a bubble that's red on Charlie's ear? This is on right at the side, not really in the ear canal itself. Sadie's ears are red down in the canal itself.
