Hi all,
While I was giving Willis a brush last night, I was checking the insides of his ears, and noticed that one of them had hard rough skin inside,but greasy too (hard to describe)
Have any of you any advice on what it could be? I cleaned his ears carefully, and some of it did come off, they look better today, but there is still some left.
Could it be a yeast infection??? I read on the net about yeast infections, but not sure this is what he has, it says for a yeast infection to clean his ears around with vinegar.
