My Mini has begun rubbing his tail out! I have owned this horse for 16 years and he had never done this before until last summer. Below is a list of things I have ruled out and tried, I'm out of ideas, if you can think of something else PLEASE HELP!
Has never missed a worming in 16 years. Wormed on a rotation.
Haven't changed hay supplier in 3 years
I use minimal fly spray, because one of my other horses is allergic, when the rubbing started I tried using a lot more on my Mini, especially his tail.
Also tried not using ANY fly spray, no difference.
Rubbing discontinued briefly during the fall, started again in January. So I don't think its bugs bugging him.
Tried conditioners, shampoos & lotions
Dex shot and cream (AKA Benadryl cream)
No bedding to be allergic to, he's always turned out.
Supplements and grain have been the same for 5 years.
I should also add, last August he had some weird allergic reaction where he swelled up everywhere, especially his sheath, that's when the tail rubbing started. My vet, said allergy triggers in horses are nearly impossible to find. He gave my Mini a couple doses of Dex. And the hives and swelling cleared up with no return, but the tail rubbing continues. Could it just be a habit now? He used to have a beautiful little tail, but now his dock is hairless. Can any one here see what I may have missed?
