Am I being over worried??

[Quartz]

Just been to feed horse his hay, and gave him a stroke to find he was sweating. I know its slightly warmer and he had been standing in the sun, but still sweating for him is pretty unusual. He didn't do this when it was in the high 30s this summer. There was a tractor in the field next door with the other horses so wonder if he just got a bit stressed with something going on over there or over excited. I have checked and no signs of diarreahea, no runny nose (other than the usual), checked all over and no obvious signs of anything. Felt the base of ears, OK. Was just his sides, neck and by his sheath. Am I being over worried?

Has he started to grow a winter coat? That could account for it.

 

[Quartz]

Yes he has. It has been quite cold, but right now its almost 23 degrees in the sun.

He' s probably fine, he probably got excited by the tractor and had a gallop around.
Just keep your eye on him to be sure.

I would have thought he is fine. If he has his winter coat and it is as warm as it is here then that along with a run around would have made him pretty hot. Just give him a pat and then remember to breath!
