Anhidrosis, HealthyCoat, and My Horse

Prior to August of last year, I was not familiar with a condition called anhidrosis. If you have never heard of it, this occurs when environmental conditions trigger something in a horse that leads to a diminished ability to sweat. Flashback to August of 2018 after a long search for my daughter’s next horse, we were presented with the opportunity to try a “non-sweater” in Florida. Having never heard of this condition, I started my research. While the exact cause is not fully understood, an overactive adrenal response to stretches of high heat and humidity seems to play a part in the development of anhidrosis. Horses with this condition display symptoms such as dry, flaky skin, exhaustion, increased respiration rate, poor appetite, and little to no sweating. Of course, when buying a horse, I’m never looking to buy a “problem”, but I felt that this was a condition we could manage if he was in fact the unicorn we’d been waiting for!

Upon arrival to Florida we noticed the classic symptoms in this guy. He was not sweating at all in the heat and humidity. His coat was thinned and flaky, and respiration rate elevated. He could only be worked for short intervals in the morning or evening, when wetted with water. Anhidrosis symptoms aside, he was exactly what we were looking for and my daughter fell in love with him, so we took a chance. We moved the him north to our home, and he started on HealthyCoat in his feed ration in March 2019.


HealthyCoat can benefit “non-sweaters” in multiple ways. First, it is rich in Omega 3 and 6 fatty acids. These essential fatty acids help the body in many ways because they lead to the production of hormones that help control inflammation, repair tissues, aid in brain function and repair of cell walls. HealthyCoat also aids in the digestion and absorption of fat-soluble vitamins A, D, E and K. It is great for hot weather feeding, because it adds calories to the diet without producing heat during digestion. Additionally, Vitamin E has been suggested to be helpful in improving or restoring a horse’s ability to sweat.

We are now into mid-July of 2019 and it is amazing to see the difference in our horse’s coat this summer! He still has a higher respiration rate during hot, humid stretches (like many horses) but he has not lost all ability to sweat. His skin and coat look fantastic and he has not become dehydrated or suffered from a loss of appetite. I truly believe that HealthyCoat is helping him manage this hot, humid weather. I, like every other owner that has wrestled with this condition, wish there was a simple solution for anhidrosis. We can’t control the weather, but we can manage our “unicorn’s” environment and nutrition to optimize their chances of a healthy happy summer!
