Hey all! I read multiple posts on this but wanted to get some fresher feedback. I am noticing my fairly new OTTB having a bunch of flaky skin buildup in certain areas. I notice it on his shoulders, neck, and legs especially. Mostly around old scabs and wounds that are growing back hair. He is still shedding his winter coat and its gotten much thinner and more sparse in areas. I have a photo you can kind of compare to the horse beside him (he is on the left) and the mark on his shoulder barely has any hair...just long, thin hair. You can also tell he is losing hair on his face, and is missing a lot of hair on his bum beside his tail and under his legs. Also I may add I rescued him and he came in a poor state, he is still very underweight. I've never seen him itch and he doesn't seem bothered by it. I only use antifungal medicated shampoo on him and have only bathed him 3 times since I got him in April so over bathing isnt the issue...we recently switched his feed and saw he wasn't gaining any so we put him back on the stuff he was fine with before and showing good results. Could it just be a buildup of skin from shedding? I'm hoping his thin hair will shed out and he'll grow a nice summer coat =/ I created a DIY skin serum with baby oil and vitamin E which I've had luck with in the past for great coats but I'm worried he's going to shed out all his hair and be bald! (Crazy, but new horse mom problems) I also heard using Apple Cider Vinegar works for this. ANY KIND OF FEEDBACK would be great! Sorry for the not so great photo...just imagine a lot of dandruff build up and thin hair loss.
