She does (Westfall Horsemanship
), but I don't get the marketing sense that she's trying to get anyone comfortable with starting a colt.
I don't object to someone having DVDs about starting a horse, provided they don't make it sound like anyone can do it. I've got some DVDs from Larry Trocha, who also has colt starting DVDs, but I don't get the feeling he is suggesting anyone can start a horse and "magically" succeed.
I think DVDs are great for trying to work a problem area or expand the teaching of an already good horse. Mia might be a PITA at times, but she knows the basics and is fundamentally a sweet & willing horse. I think it is OK for me to work on her balance in turns, or try to improve her stops. But when she was an uncontrollable mess, she needed a pro. Not a DVD, but a pro.
My main objection to Parelli is that he seems to market his stuff to inexperienced people who are afraid of their horse or even who need to train a green-broke horse. I honestly think that, in that situation, a person is better spending $50 on some trail shoes, and leading their horse on a lead rope. Start at a distance you & your horse can handle, and work up to 2-4 miles. I think regular 4 miles walks with your horse will teach a newbie (like me) more about your horse than any number of round pen sessions or poking it with a stick. Walking a horse is a good way to learn to read it, and comes in useful if you ever end up needing to lead it somewhere on the trail. Then
they need riding lessons...
