No Sweat....No Poop?

So after being with him all afternoon, I have an interesting observation to share. He didn't sweat or poop during the whole ordeal. I know he was terrified being put in the trailer, and at the very least, "unconfident" in the trailer for a 45min drive. He was dry when he got out of the trailer and there was no poop. Then I thought about it, he didn't poop the whole 2hrs during the loading process. He then did not poop till later in the eve. So no poop from 10a to 6pm. He did not appear stressed at all once home. This morn there is a nice heaping mound for me....BTW he is a tidy pooper, one spot only.... My older TB mare has severe trailer issues and no matter how cold or confident she is, she still has the usual nervous sweat pattern and water poop when trailering. I have been around alot of nervous horses in my day, and most (untill today I thought ALL) horses have the usual sweat pattern when nervous. He had NONE. Not even a little around his ears. Right now he is a perfect right brain horse and has dots equally between intro and extro. Something odd to lick and chew about for sure, though I doubt I will ever have an answer. So I thought I would share.
Savvy On
