This is a just for fun post! What unusual, odd, funny, annoying, etc. quirks do your horses have?
For instance, I have a ottb mare that will suddenly throw herself down to her knees when she’s overly upset/frustrated/overwhelmed by something and stay there with her bum in the air. I’ve come to recognize it as her way of saying “too much” & shutting down. (FWIW she’s never done it under saddle & it’s becoming less frequent as we continue developing our partnership). I certainly don’t encourage it but it’s odd enough to make me stop what I’m doing & laugh enough to remind me to take a step back & re-evaluate how she’s interpreting the current situation
