wow! Thanks to everyone for your quick replies. He will eat human food, just not his dry dog food. I have tried changing it, but it doesn't help. Sometimes he will eat wet dog food, but he just seems to be very picky lately. This has been going on about a month. We just finished the ear medication, but his ear still looks a little red to me. His energy level has been pretty normal. I know it has been very hot, so I think that might have something to so with his lack of eating, I am hoping that is the reason. He exercizes a LOT, so that may have contributed to the weight loss, probably of about 10 pounds. I think he is a little skinny, but other people say he looks normal. Maybe I am worrying over nothing, maybe he does need more medication. I will try to take him to the vet again. Is it possible for a dog to get too much exercize?
