The difference?

Any training program can put the horse first, but its all up to the human involved if they want to do that.
Someone with parelli may want to just progress through all the levels and not care that the horse is still scared of the carrot stick or anything like that, yet someone with a different training program will make sure the horse is always put first.
Did that make any sense? I hope so

No no no, not at all. Sorry if that's the way it came across. I do know that other trainers, like Denis Reis, have the horse's best interest in mind. I love Denis, I think he's great.....a little boring and monotone, but a fantastic horseman. He's not for me, but I have a ton of respect for him.

Let me see if I can say this next part right.....for me personally, I feel Parelli has the best deal for the horse, otherwise I wouldn't be following it, however that doesn't mean I look down on people who don't follow Parelli. I only look down on people who don't care about the horse and treat them like robots, the people who really don't love the horse, they are just using them to fulfill some personal need for feeling powerful, in control of another being or just wanting to WIN....at any cost. Does that make sense?
