Seems to be doing the trick
I’ve got an older retired reiner here in Florida that all of a sudden stopped sweating. The lack of sweating caused him to breathe abnormally heavy because he couldn’t stay cool. I panicked. Someone had suggested this product and it’s definitely helping. Not sure if his body chemistry just needed to be kicked into gear, but he’s back to sweating appropriately for the temperatures and humidity here.

One-AC starts my horses sweating again
When horses stop sweating in hot weather (anhidrosis) this helps then start again in about a week. It’s worked on 3 different horses in the past few years. I always keep a jar on hand.

Such a great product

Worked for my pony
I know from experience that this product works for some horses and not others. I double dosed my pony to get her to start sweating. Now sheâs on a maintenance dose. I also increased her her salt intake and electrolytes. I think all three together are what did the trick. What I really liked about this product from Amazon, is that the price is fantastic.

Horse went from not sweating to almost sweating too much
This stuff worked well My OTTB wasnt sweating much and after a week of this he was almost sweating too much.
Kathy Sumrow –
Seemed to work.. took about a week.
My old horse is Cushingoid and lost the ability to sweat this year. This helped a bit. At this point I’ll take what I can get. I did get him to actually sweat in full by adding Sweat Well from another manufacturer
