Lucky started having ear issues last week. He had one red post inside his ear that he kept scratching and made bleed. He cannot stop scratching it. I got hydrocortisone creme and ear cleaner to try and help. None has helped. In fact, this morning I checked his ear and he has over 25 red bumps. I don't know what it is. What should I do? I also need to mention I work 30 minutes away from home and my vet. Thanks!
