View Full Version : Overheating...

Of my 3, Duchess is by far the darkest. She also has a much shorter, softer coat. In summer you can always tell that her skin is black underneath, because you can see the skin itself. I don't know, but I think that this darkness of coat and exposed skin may cause her to feel the heat more than the other 2 (a bright red bay and a pale chestnut).

It may be something less obvious; I have no idea. She sweats almost as much as the other two; she stays in the shade most of the time, so I think that's why she sweats (just a little) less--her neck and shoulders are covered with sweat when Kat's neck, shoulders, and some of her barrel are all sweaty. So I don't think she's anhydrotic. I can't think of anything else that would commonly make a horse more prone to overheating.

She is so, so hot. We spent a while out there watching her today; she stays in the barn where it's cooler, and even inside she blows/veins stick out like she's just run 30 miles. She seemed a bit happier when we hosed her down (still in the stall, in the shade), but she didn't stop blowing.

We're talking about piping water over to the stalls and putting in a periodic mister. We did some preliminary PVC plumbing today (finally installed a spigot that is OUTSIDE of the barn) and I don't think it would be terribly difficult, but supplies might be a bit expensive; fortunately the water would be from a well. May not happen immediately...and judging by the little that it helped today, it may not be enough anyway.

Anyone have any other suggestions for me? This poor mare is SO hot. Duchess is always whiny about minor injuries and discomforts--she seems a bit more sensitive than some horses--but this is legitimate distress, even if she just feels the heat more than the other two.

Edit: I have a few box fans, and was looking at the barn today to try to figure out where to put them. Due to the bizarre construction in there, I couldn't come up with a way to put in a fan that would be safe for the horses. I'm going to keep looking into it, but until/if I figure out a way to put one up, it's not a potential solution.

First off anhidrosis comes in different levels. It's not an all or nothing issue. DJ sweats a little, just not enough. Do a search with it spelled with an 'i' instead of a 'y' and it may come up with more articles on it.

That being said, hosing him down really does the trick for us. If he is really hot I horse him down first, then sweat scrape him to get rid of the now warm water on his body and hose him a again. By the second one even on hot as %^& days, he relaxes, his nostrils get small, his breathing normalizes, and he starts showing signs of being comfortable.

For DJ's field shelter we will install the Cool Corral system because it only needs water/ not electricity: Corral Cooler (http://cooler.countrysupply.com/)

For the stalls we will use the fan and water system since we will have access to electricity there: Arctic Circle (http://www.valleyvet.com/ct_detail.html?pgguid=30e07530-7b6a-11d5-a192-00b0d0204ae5)

Sorry to be of not much help. Evaporation cooling is really the only thing we have come up with as well.

Strange that the hosing doesn't help her...

When she works, when she's out, she sweats--a lot! In general she's less sweaty than the others, but like I said, she's staying in the shade standing still, while they're in direct sunlight moving around and grazing. (& it is 5-10 degrees cooler in the barn than outside) I'll take a look anyway--thanks for the good suggestion, maybe pages on anhidrosis would have more suggestions about keeping horses cool.

She already gets extra salt anyway, all 3 do (like is suggested in the thing on anhydrosis recommendations that I showed you). And having spent a while tracking her water intake, I don't think she's "subclinically dehydrated." We put in an automatic waterer today because the 3 horses are draining 3 muck-bucket sized tubs between AM & PM feedings; when they all go to drink, Duchess makes the others wait while she drinks, and she usually drinks for longer than the other two. So I don't think she's overheating due to lack of liquids...

She did look a little happier when we hosed her off, but not much :(

The "Corral Cooler" looks similar to what we were talking about putting in. Perhaps if we can get the temperature inside another 5-10 degrees lower she'd be happier...

Or maybe it would just be easier to put in a heavy-duty waterproof flooring in the enclosed porch and keep her in the AC all day ;) ...would be nice if that were an option.

What about popping a white fly rug type thing on her to reflect the sun rather than her coat absorbing the head?

I know it can be a little difficult for you guys to recall that the Florida climate is so different from yours. My horses sweat under their fly masks! I think a covering of any kind is definitely out of the question...

I don't really have any suggestions for you as it sounds like you're doing everything I would have thought of already. I just wanted to say that Bebe is very similar to your mare. She has black skin and gets incredibly hot to the point of her veins popping out and her being obviously uncomfortable. She does sweat, it's not unusual to bring her in from the field slightly sweaty even when she's been stood in the shade, and she'll also sweat in her stable which is always much cooler than outside (and shaded as its indoors). I've taken to hosing her neck, shoulders and up between her hind legs before riding if she's sweaty when I bring her in, and I try not to ride during the hottest parts of the day. She has electrolytes after work, normal salt if she hasn't worked and doesn't ever appear dehydrated.

I don't know if the black skin has anything to do with it, though it does make sense. I was seriously considering clipping Bebe out a month or so ago but we've had a spell of really cool, wet weather so she's been okay. Other than that though, I don't know what to do.

Fly rugs make her hotter too, even white ones.
