Sweat... What Does it Mean?

For the past two weeks, Jerry's hindquarters have been VERY sweaty when I get off. Last week it was nice and cool, and he was still quite sweaty. This week it has been more humid, and there was more sweat, but he has never really sweated on his hindquarters before.

So what does sweating on the hindquarters mean?

Most likely that he was working and got a little warm. More warm more sweat.

It might actually mean you're working him more effectively. If it's butt sweat, as in between the cheeks, it basically means he's pushing himself properly from behind instead of pulling himself along on the forehand. It's good sweat!

^ Yeah, that...

However, that said, if he is sweating in a weird pattern somewhere, he may have some sore spots, or something, causing him to sweat more in particular spots, rather than evenly. However, as long as he seems to be performing the same, and isn't 'off' at all, he is probably just reacting to the extra heat, and humidity...tis the season!

Ditto all that. I have one horse with an injured sacrum that, even at liberty in the pasture, if he's not feeling well will sweat profusely from the top of his rump all the way down.

I have another one that I rescued who has an old vertebra injury. His entire hindquarters will sweat profusely (including underneath) at liberty when he is stressed and needs an adjustment. Soon as the chiro adjusts him, the sweating goes away.

All horses sweat differently. Some hardly ever sweat at all, some sweat profusely from head to tail, and some it's actually relative to the work, lol. As M2P said, as long as he's his normal self and doesn't seem to hurt [perhaps you can palpate the area] he's just sweating.
