Ace does have a small sore on his ear. The breeder said it was where the other puppies had been playing and nipping each other. After getting him home and examining it closer the next day, it appeared to me like a hotspot so I treated with and antibacterial and hotspot spray, it didn't get any worse but on examination today the Vet said it appears to be ringworm. So she recommended some otc fungal medication for humans. I had some lotrimin cream and so applied some of that for the time being. Any suggestions out there?
