My joey has a few (not bad) dry cracks on the outer part of his ear. The inner part is fine, I didn't see anything visibly in there though I know with a scope, the vet could see better. Could this be a s/s of parasites. I took pictures that aren't that good but don't know how to upload to this forum. He is getting well, no weight loss, no loss of activity or any other s/s of illness. He just had a vet check about 2.5 mths ago.
