My dog has foot blisters and now an ear infection, can anyone tell me what might cause these symptoms? - foot blisters

My dog has recently announced the blisters on his feet, now has an ear infection. He is allergic to fleas, but the advantage is primarily the years. I love my dog, and take good care of him, but is very expensive, if you take him to the vet. Can someone me an idea of what could be the cause of your problems?
