When do you scratch due to heat?

Good post Storm Cadet. I didnt even think about the possibility of a horse not sweating when they are suppose to. And one would come to the conclusion that a horse should sweat when they are on a track that is 100 degrees. It is only natural. And if they do not sweat, then they have to be out of fluids. There is no other reason for them to sweat.

I am more on an expert on the human body and not the equine body. And it is always the case of a person not getting enough fluids in them when they come to see me and state that they do not sweat. "They" think it is because they are in good shape. I tell them NOOOOOO!!!!! You should sweat more when you work out because you have to get your body hydrated and more importantly oxidized.

Will be interesting to see if any tracks on the east coast shut down today with this 100 plus heat. They are closing down schools today and sending kids home in tri state area, something that we don't normally see.

not sweating when you're supposed to is a sign of heat stress, or more seriously, heat stroke-which is deadly. i would imagine it would be the same in horses as it is in humans.
i saw them laying whole ice bags on some of the horses backs when they were walking from the track back to the barns.

i just think a combo of things affected big brown, and in total, was way too much for him to overcome. they may never find a reason why-as they're looking for one big thing, and i think it was many little things ( or maybe not so little) combined that kept him from the win.

We had a thoroughbred that wouldn't sweat ... it was never a good thing in the summers down here with as hot as it gets. He was constantly blowing (breathing heavy.) We had him on a supplement called ONE AC and it seemed to help a bit, although it didn't completely correct the problem.
