Not my uppy ear buns, but Mimz has these knobby dry spots on the bottoms (well, tips) of his ears and some dry-ish areas on the inside ends that the doctor has looked at and found no mites, but they don’t heal no matter what I put on them. If you pick at the tips they will scale and then if you’re persistent, they bleed, 0_o, so what I’m thinking is with the way he washes his ears furiously and many times over the day/night, he must be chewing them a bit and the rough edges are just scabs from that. Plus they drag on the floor when he sits down, so who knows what kind of abuse they take there.
I’ve seen flakes on his skin as well, but none of them walk away, and there’s no sign of bug poop. >.<
I think all my buns have had some dry skin at one time or other, but I don’t see it happening with all three at once.
Although with our weird humidity here (high one minute, very low the next) I assume they are all a bit dry. If their water intake is any indication, anyway.
