I just recently rescued a 2 year old paint stud colt, we have started his training and today he finally conquered lunging. He has not been started under saddle and he has never had a bit put in his mouth. So my question was that while we were lunging, he pulled back the corners of his lips to show his top
Row of teeth. He didn't have his lip curled back or anything, it was sort of like he was smiling. But while he was doing it he was chomping his front teeth pretty quickly. He didn't quit until we were done with excersise.
This is not the first time I've seen this. My cousin used to own a 1d barrel horse who also did this same exact thing. She had no health problems either. It always got me curious on what it meant And why she did it. Is it just a habit? Or does it mean something?
