Anybody else's horses shedding out to bald?

My gelding usually sheds pretty normally in the spring. Now, he’s an itchy, sensitive-skinned Appy, so by mid-to-late summer he’s rubbing and gnawing himself bald/raw from insects and heat and what-not, but springtime usually isn’t an issue.

A couple of weeks ago he got what looked like maybe rain rot around and a little bit on the dock of his tail. He’s never had rain rot in his life (I’ve owned him 16 of his 17 years), but I washed and treated. It cleared up pretty easily and hair is growing back in VERY slowly. I also thought maybe pinworms, so hit him with Equimax, which I normally do in later spring, but whatever.

That has cleared up and he’s been shedding like crazy, but he’s dang near bald over his loin, between his back legs, on his shoulders, and chest. It’s not unhealthy looking, skin seems fine, it’s just so weird! It’s like he blew out his winter coat before his summer came in.

It did get unseasonably hot for a spell (highs hitting 90 a couple of days and humid) and that’s when he got his first bath of the season and the hair started going bye-bye.

He’s on a very good diet, lots of Copper, Zinc, Biotin, Vitamin E, etc. 24/7 turnout with access to nice shelter, a little grass but not much, very nice hay, and I’ve added spirulina since the itchy/hairless situation. He IS itchy.

The only things I can think of are the hot weather spell we had AND I had kept him off of any soy for a few years and now have reintroduced it. My thinking was that soy never made him itchy in the winter back when I used to feed it, so it probably wasn’t the cause of his itchiness anyway. He itches in the summer with or without soy, so I just don’t think that’s the likely culprit.

Anyway. Just wondering if others are seeing or have seen this shedding to baldness before. I assume his summer coat will come in and he’ll be just fine. At least I sure hope so.

Yep. I had a horse that did this every spring as he got older. Wasn’t anything wrong with him. His summer coat did come in, it just lagged a little. I know it’s very weird to see, especially the first time!!

Might be worth a Cushings test if you haven’t already.

My old leopard appy used to do this. He’d shed his summer coat before his winter coat came in, leaving some very sun-vulnerable pink skin at the end of August.

I’d run a cushings test, with the benefit of hindsight.

This - when my old TB gelding got his cushings dx, he would shed out and be covered in bald spots. It was rather alarming but his summer coat did grow in eventually.

No idea if it was related to the cushings or not but it only started once he had it.

Yeah, I’ve had a Cushing’s horse that did this, but it was a little different than what this guy is doing. My Cushing’s horse was pretty typical: started out IR, fat pads, then lost condition and top line, hair coat went to hell, shedding started being irregular, sore feet, etc. Then one winter in February when it was literally snowing, he was shedding ALL of his hair out. Like I could just stand there and pull it out right down to the skin with no effort at all. He then regrew his winter coat and didn’t shed properly until mid-summer.

This horse shows no signs of anything metabolic or PPID. Strong topline, excellent body condition, sound hooves, and his shedding was normal until that hot spell.

Also of note is that he’s shedding in all the places he usually sheds (on each end, saving the middle for last). It’s just that he’s so…hairless. I mean there is hair…just very little.

He’s never been one to have a thick winter coat anyway. I mean, he’s got plenty to stay warm, but he doesn’t get super hairy.

I’ll keep Cushing’s in the back of my mind though, of course, especially as he ages.

Hi, someone who owns a cushings pony with excellent top line, shiny coat, good hooves and all that normal pony stuff they can have cushings while being in excellent condition. We were testing early so we could catch it fast and his only symptom is growing a long coat. It’s not even an unhealthy looking coat just long. Early detection helps a ton for avoiding a lot of the worse symptoms. We started testing at 17 with a diagnosis at 19 and immediately started medication. But my main point is cushings the thought is oh they don’t shed but it’s really that they shed weird. It doesn’t hurt to start testing now for early detection because then you can get ahead of it and deal with minimal symptoms that really doesn’t affect the every day life

I had an app that shed first and then grew his summer coat. It bought him some time off because I couldn’t bring myself to put tack on him near naked.

He could be and probably is just having an awkward hair growth year, since it sounds like he had skin trouble, but agree that it never hurts to get a baseline test for metabolic issues- especially since he’s never had skin trouble before in his life, either.

Oh, he’s definitely had skin issues. He’s a walking skin issue. LOL. Just never at this time of year and never really anything that looked like what happened on his butt/either side of his tail.

But he’s an itchy, rubby, lumpy, bumpy, scabby mess in mid-late summer. Sweet itch, allergies, etc. Oh yeah. Runny eyes. The whole nine yards. He’s allergic to the world. He also has anhidrosis and we live where it gets to triple digits with awful humidity.

I’m thinking the unseasonably hot weather may have had something to do with the mega shedding to near baldness.

He has a turnout sheet on today because it’s windy and in the 50’s and he’s nekkid!

Fwiw there was nothing cushingoid about my horse that did this. He also didn’t have any particular weird skin stuff in general. It was just his thing :joy:
