We have three dachshunds, Dooley, Dink, and Tess. Dooley is 18 months old. A couple of weeks ago I noticed bumps on the lower third of his ears. He was at the vet for a check-up and booster shots a month ago and the vet didn't mention them, so I guess they weren't there then. On one ear they are mostly under the skin. On the other ear there are a couple that look kind of crusty. All dogs have the same parents. Dooley has always had allergies--coughs/sneezes if he gets in long grass. No signs of bumps or allergies with the other dogs. They all take Interceptor flavor tabs for heartworm prevention and eat Diamond maintenance food. In the summer we use Atvantage for fleas but haven't done that since November. They don't have fleas now. They are inside dogs. Does anybody have an idea what the bumps could be? I thought I'd try home treatment before taking him to the vet.
