Our cocker spaniel, Cinnamon, has horrible smelling ears. I bring her to the vet, they prescribe an antibiotic and ear drops and everything is fine. As soon as she is off the antibiotic everything returns over and over again. Is there anything we can do besides going to the Vet over and over again?
Try keeping some of the medicine around so you could put the medicine in the ears a few times a week (2-3x), even when the infection is gone. This will help control the problem. I also recommend that you talk to your vet about a surgical proceedure called a lateral ear resection. Good luck, vetcare
