My shedding horse is going bald

All three of mine were doing weird things. My super fat healthy mare had a bare butt for a week. Rick's forehead went COMPLETELY bald but he was fine everywhere else. My grey gelding was really weird and had bare patches on his flanks.
It's the weather. Lay off the curry comb on the thin area, their skin is sensitive and could even be sunburned. My grey was super sensitive so I just used a soft brush and let things happen naturally with him. He's lookin sharp now.

What puzzles me is that a horse starts it's new coat about December. We just can't see it for all the winter coat. Shedding is based on daylight hours getting longer, not temperatures. Why would only some horses have this condition yet not all? Why her and not mine nor the other neighboring horses? Yet those who have it are spread about a huge geographical area with different weather patterns.

A horse at our barn is shedidng like that. He looks so sad haha.

Hi, I've just experienced the same thing with my 26 year old chestnut mare here in the UK. Her hair around the stifle, in & around the hindlegs fell out in huge patches leaving dry bare skin. It looked like mange (!) but she wasn't itching at all & couldnt have reached to have rubbed some of the areas bare.

This started before we put the clocks forward but we've had a unseasonally warm spell at the end of our winter & after doing some investigations online I came across 'Equine Seasonal Alopecia' (dont think I can insert url's so just Google it). As other users have posted this is where the winter fur sheds before the summer coat has started growing.

My mare lives out & to be on the safe side I added a broad spectrum multi-vitamin & some cod liver oil to her twice-weekly feeds. After around a month the hair started to grow back & has continued to do so. Looked awful at the time & still a bit odd with patches of summer coat with long furry winter coat but nothing serious I don't think.

Weird! My Paint gelding is black and white and in his white you can see his pink skin clearly! He was at the trainers for a month got him back about 5 days ago. And he looks ready for summer but with very short hair on his neck and stomach/sides. While my other two are still shedding!

Ive noticed it more on my darker horses. Maybe they were getting warmer? Not sure. My lighter white type horses don't have any of these issue.s

Yep, I'm having the same problem with my 23 year old chestnut. His face started getting bald and then his shoulder area. His skin looks healthy, I've just stayed on top of brushing him and also washed the areas with an antifungal shampoo just in case. He's got summer hair growing in but very slowly. It's got to be the weird weather this past year.

Saddlebag I agree. It is weird, I thought diet at first but my really healthy mare that I've had for years did the same thing as my newer geldings. All three were on good pasture this winter with added hay, minerals, and feed. Cherie on the other thread said a deficiency but it shouldn't have effected my mare if that was the case. Idk! All I know is I was freaking out thinking they had lice but they didn't. Weird.

One of the boarders horses here, a chestnut gelding, is doing the same thing. The other nine horses (not chestnut) are reasonably normal, for the most part. One of my friends horses, another chestnut, is going bald also.

I got this off of another group I'm a part of... Seems like it is a wide spread problem... Not sure this is the answer but maybe worth looking more into....

Anyone ever heard of seasonal alopecia in horses? Where the horse is going bald in spots. Clumps of hair falling out. It is because it got hot so fast and the horses haven't had a chance for their summer hair to grow on and it is making the winter hair fall out in clumps. That is going on in my barn right now..no treatment ...it will grow back on its own, but I did buy some mtg to help summer hair grow faster. I thought I would let you know because I have never heard of it and thought it was interesting.
