Our last horse, Felix, is at Best Friends now. The previous owner damaged his esophagus through abuse and we didnt know about it until he started choking on his food. It was deemed too dangerous for him to make the journey from Utah to NC when we moved (might choke to death in the trailer on the way), so we had to give him up. He gets really great care there. We will be visiting him soon, and Ill get to see Vick's dogs for myself. We could conceivably adopt one, as we are starting to talk about another dog, but not sure about that.
In Parelli training, when you look 'with intent' at either the shoulder or the rear/hip, the horse should move that part of his body away from you. You are mimicing what a boss horse would do to get another horse to comply.
Funny wording though
This info is from my woman, I dont know the first thing about horse training personally.
