My Lhasa Apso had chronic ear infections. After trying several different medications, the vet tested the smelly, runny discharge from her crusty ears. She had multiple colonies of bacteria including staff and strep etc. We did the best we could for quite a while and then I changed veterinarians. The new vet prescribed quite a bit of thyroid and her ears cleared up immediately and stayed clear as long as she was on the thyroid. Thyroid medication cured the ear infections.
