I am by no means a vet, but you could get an earwash and rinse/clean them out good. I have also found a good home remedy for ear infections. Actually my vet told me about it believe it or not. My vet was repeatedly treating a cocker spaniel for ear infections (they are notorious for ear issues) and then one day the owner came in with the dog again. The vet assumed they were there for the ears again. The owner said nope... Her ears had been fine. When the vet asked what she had been doing she said she had been using a home remedy of vinegar and water. I have tried it on my English setter and it WORKS! You have to be careful and catch it before the dog scratches and cuts the inside of the ear b/c of course the vinegar will burn like fire. The dog may smell a little from the vinegar but it is easy, inexpensive and it works in my experience. My vet said he was so impressed with the state of the dogs ears, he was going to tell his other patients that struggled with this about it. That's why he shared it with me, thought I would pass it along. BTW, it takes very little vinegar maybe a teaspoon or 2 to about a full 12 oz bottle of water. I still use the same earwash bottle I had, I just keep the home remedy in it now instead of purchasing more and more earwash. We really haven't had any ear infections in years. I think he may be getting one, I use a little of this and problem has been solved.
