One of my horses was a stallion for 6 years before an attempt to geld him && he is now still retaining a testicle so he's proud cut && the crest of his neck is very large, I do trim a 2 1/2 inch bridle path but no more because he is very thick maned but an inch of where my bridle lies is going bald, why is this and what can I do? My bridle fits properly so what is going on?
Could he be rubbing his head on a tree or something in his stall. Some horses rub out their tail if they have an itchy butt. Maybe he has gnats in his ears so he's rubbing his head in attempt to scratch them?
