For some reason my horse is loosing hair. It started just above his left eye in a patch about 2" by 2". Now it seems small patches are falling out in several locations. His skin seemed really dry and has had excessive dandruff that I had assumed was due to the cold dry air we had a few weeks ago. The skin where he is balding looks nice an healthy and the dandruff seems to have subsided but he is still loosing hair. I thought maybe rain rot but there isn't really any scabbing. I haven't changed his diet an he gets brushed out 4-7 times a week. The brushing now seems to irritate him. Any thoughts? I'll try an get some pics up soon.
