Ever heard of anhidrosis?

My 28 yr old Thoroughbred had an episode Friday that we thought was heat exhaustion but he recovered with less than an hour of cold hosing without being giving any fluids. He also showed no signs of dehydration. We had noticed that he wasn't sweating until after we hosed him. Saturday he began showing signs again so we started cold hosing him and he was fine within a half hour or so. Yesterday the same thing. Today I hosed him before he started acting hot. Each time we have noticed he is not sweating until after we hose him and then he isn't sweating like a 1400# horse should be in 100 degree heat. The vet is thinking he has developed anhidrosis which is when the body no longer sweats. Has enyone ever dealt with this? I've done some research and found it is most common in Thoroughbreds but usually when they change climates or are worked when its hot out. My boy has lived here at least 6 years that I know of and outside of an occational ride in the fall he hasn't been worked at all.
Any comments or info would be greatly appreciated. This horse is my love and I worried sick. Thanks

Yup, my gelding has it. We give him electrolytes in the am, Epsom salt in the pm, he gets hosed before and after a ride, as well as several times a day.
Oddly, I just changed his food from Strategy to Nutrina Lifestyle Compete and he is sweating a storm now, dunno if it's a coincidence or not, but I'm thrilled to have it.
We jump started him with beer and a sugar salt mixture. Some times a product called 1ac works with these horses.

Yes, actually I found quite a bit of info about it while researching the opposite problem that our TB has - she is a SWEATER!!! I didn't read/absorb too much about your boy's condition for the simple fact that it wasn't what I was looking for -but there is a lot of information out there to be had via google, etc. Good luck to you and your boy

Theres some stuff called AC-1 that people use for this. From what I understand, even if your horse stops sweating one summer, their systems can "reset" and the next summer they may not be afflicted with it. I've seen a few horses with it here in Florida. Gotta keep em cool, shaded and hydrated. I've heard the beer works too.

Some vets believe that anhidrosis is brought on by being overworked and overheated. The sweat glands become exausted thus becoming less responsive and permanent damage ensues.

Sometimes horses with anhidrosis sweat ...but in odd areas or small patches. (horses can have anhidrosis and still sweat but in smaller amounts)

What I would do if I thought my horse had this condition? Call the vet and he can perform a simple sweat test.

If posititve...

You can start working your horse early in the morning or later in the evening when it is cool. Make sure you give plenty of walk breaks so as to not overheat the horse.

Turnout at night if possible to avoid overheating during the day.

I heard that Guinness (yes the beer) does wonders for horses with this condition just apply it to the feed.

Also as another person said make sure your horse has salt available ( I feed LOOSE salt it is easier for them to get the amount they need )

Yes my gelding did this and we watch him every year. We gave him 1ac, beer, salt and a ton of other stuff. He sweats now but we are always making sure he is sweating.

My horse has this and I feed him 1AC. I think it works great for Spring and Fall so that I can ride but I'm seeing that it's not helping a hole lot during these hot days we are having right now. Right now I try to just hose him down when he gets overheated and keep a good eye on him. He just developed this 2 years ago when he turned 11. He's never been worked much, I just trail ride him when I have time so I know it can't be from to much work. I can't help but wonder if it's genetic.
I'm definitely going to try beer in his feed and see if that helps. I'm up for anything that might do the trick tho. So any suggestions are greatly appreciated.
