I just got my first pig about a month and a half ago.since then he lost a little hair behind each of his ears. he has little dandruff like things in the bald spot (not to many of them manybe 4-5 in each) and he has a scab on his ear. if this is mites, is there any way to treat them at home? I gave him a bath today, but was wondering if there was anything else I should do for him.
