But now he is rubbing his butt bad...not his tail, that is still fine, just his butt so whatever he is rubbing on he is flipping his tail over it. At least I THINK he is rubbing. It started in small patches on each cheek and yesterday covered a good 2"X4" area on each one. This morning I get there and it's now down his legs. I can't see anything except what looks like very very dry skin and what is getting to be an area that looks and feels the texture of beef jerky. Sorry, didn't think to take the pics until after I put MTG on it.
I walked the fence line and can not find any signs of him rubbing except maybe a broken off branch in an evergreen tree and there is a really old wood support in a corner that looks like it's taken some recent damage...not chewed but the wood definitely looks recently damaged. We scraped some of the dandruff off and looked at it with a high power magnifier and it just still looks like skin. Nothing creepy crawly movin around.
He has been at my friend/trainers house for a month. He is in a pasture with just Brom that he can eat to his hearts content and I make sure he has fresh water daily. My friend told me today that she thinks there might be some St. Johns Wart in there somewhere but she has never know it to cause this. Before he was moved to this pasture he was in a dry lot with a round bale that was predominantly Brom.
This started before I EVER bathed him myself so I don't think it's shampoos or anything. Bathing doesn't seem to help. I did stop using RepelX on him because he started shortly after I started using RepelX. I gave him a good bath and put nothing on him and he seemed okay for a day or so and then the rubbing started up again.
Has anyone seen this before? Does anyone have even a guess at what it could be?
