Anhidrosis in my mini

I have a 3 yr old mini mare and yesterday when it was 100 degrees with a heat index of 107, I happened to notice that while my other horses were sweating like nobodys business, she was not. Thinking back over the last 2 yrs of owning her, I can't ever remember a time that she has sweated even after running around playing. Since she is too small to ride and I don't work her for anything, is it possible to diagnose her with anhidrosis?

Take her temperature. If it's elevated, ask the vet about it. My weather has been similar to yours and not all of my horses sweat.

I have a TB who developed anhidrosis last summer. Every body else would have sweat dripping off them and he was dry as a bone. His breathing would get heavy and if I didn't get him cold hosed he'd go down. The first time it happened his temp was 105 after 20 minutes of cold hosing when the vet got here. Since then I keep really close watch on him it the temp is above 90.
The vet diagnosed him and told me to give him a Guinness beer twice a day until I could start him on One AC last year. It helped alot. He started sweating some and had no more signs of heat stroke.

Before the temps got too high this year I put him back on the One AC. So far with heat indexes at 110+ we have had no problems. I still cold hose him and everybody else once a day but for comfort not nessecity.
I get it from but you can order it different places and it isn't expensive. For a mini the jar would no doubt last all summer. Check with your vet. I think the stuff is worth its weight in gold!

I'd make sure she was shaved down in the summer, and hose her down in hot weather. has some supplements for that. You can also mention it to the vet next time they're out.

I was reading that numerous spritzes are more effective than a single cold hosing. The article dealt with horses dealing with high temperatures. My boys have a $5 garage sale special box fan wired tight to the rafters which blows down on them That's where they stand. No matter the temps they remain comfortable.

Talk to your vet.

I will second the One AC. My mare stopped sweating last summer when it was so hot, and she was back to normal fairly quickly once she was started on the One AC.
