I went to a Tristan Tucker Response training clinic recently. I was quite impressed with what I saw. I wonder if others are familiar with his concepts and use them in ground work. His website helps explain his methods pretty well. He offers two free videos before asking the customer to sign on and pay for services. One thing I did notice I disagreed with. He discusses and teaches the horse that they are a team but he is the leader. Often, he is walking with the horse behind him. When he speeds up, the horse does, when he slows down the horse does. I thought this was a bit dangerous. I have always led the horse by their and my shoulder. I have always been taught never get into a position the horse is behind you. If the horse jumps or spooks, he'll squash you running forward. I also saw a lot of tail swishing. The horses were displaying strong swish which I interpret as agitated. He has a lot positive to his program. Especially his premise that horses are intelligent, it's up to us to teach them how to cope in our world with confidence.
