I would just suggest to go to the vet. Molly sometimes gets yeast infections in her ears caused by mites. They might give you some medicine and istruct you to clean his ears before and/or after applying the medicine. Odd question but Do his ears smell bad? Like when you are around him, can you smell some odd odor? if so then it means he DOES have an ear infection. Sorry I can't give you much help.
