Thanks guys! Yeah, I realized how tight my reins are when I played the video back. She wasn't giving me any grief about it like the others would have, so I kind of ignored it. She's a Percheron, we think, I bought her in November. The classes were mostly WP w/t, Western Horsemanship w/t, and the first class was a Jackpot Pleasure w/t with 30 entires
Myhorsesonador, I know, it was killing me because I saw so many people pulling the faces off these well-trained horses to get them to slow down. This one girl in the practice arena with me had this big beautiful paint, and she was blocking his forward motion with every aid she had, but asking for a trot with her boots/spurs, and when the horse, confused, back up, poor guy got a huge kick to the sides with these big rowel spurs. He bucked, and got another kick, along with a slap on the butt.
ETA: Actually, Wallaby, you are correct on the too-short length, but it's optional when holding split reins whether to hold them with a finger between them or not.
