Non-sweating Horses

This topic covers anything that isn’t considered normal on the skin of the horse and is not categorized into another topic.
These photos have captions to express any thoughts I have on the picture. The idea here is for YOU to get ideas, so grab a cup of coffee, darken the room, grab a pen and paper to write notes, and sit back and enjoy. I have more shots and I’ll add them later as I have time.

No Sweat!

I mean, no sweat as in your horse has stopped sweating. For anyone in the latitudes where it never gets above 85 degrees F or the humidity is moderate, you will never know what I’m talking about.

I wish I had a picture of the first horse I had actually known with anhydrosis (the medical term for non-sweating). Only his head and nostrils could be seen while his remaining body remained below the surface of the water. More common are the horses standing in front of fans, nostrils flared, rib cage heaving as they struggle to remain cool without the benefit of the cooling effect of evaporating moisture from their skin.

  1. My 14 yr old gelding has just stopped sweating. He has been on pasture and hay only for years. Other than adding salt, what else can I do?

      Discovering that a lot of non-sweating horses start to sweat after removing grain was a surprise to me. I still do not know the mechanism behind this but many people have found that it works. Now your horse comes along so let me say a few things.

      If it is true that it is the inflammation of the gut, you will need to look at any cause for this. Included in this would be: any chemicals added to the pasture or hay; increased sugar content of the spring grass; spreading of organic material (horse, cow, pig, chicken manure); anything else.

      If nothing has been added, then try removing or limiting your horse to the pasture. This can be an experiment done for only a week to test the results. If it is true that some change caused him to stop sweating, then that change needs to be found and either eliminated or addressed.

      After you exhaust all possibilities in finding the cause, you can try to add something to calm the hind gut. My go-to for this is Succeed. Get the starter pack of paste followed by granules. Be sure he is still not sweating when you add this and then record the results. If it works, the result may be permanent or you may need to continue it until cool weather come back.

      I really would like a follow up to this as you get more information. I see that you also read my other blog on this subject so be sure to comment there too. Thanks.
