"They told me they don't like a friendly, in your pocket type of horse, that they are lazy and don't work as hard for you. hmm.."
That's ridiculous. I've been working with horses for nearly sixty years now, and that's ridiculous. A horse that feels friendly toward its owner is going to work 10 times harder for him. If you work with your horse correctly, you'll have that bond. It is that simple.
Obnoxious, pushy behavior, demanding treats and refusing to be obedient, bumping into you and stepping on your feet is a TAD different from the friendly cooperative animal that greets you happily and wants to work for you.
Besides, horses are ALSO 'trained' to be obnoxious. The owners don't realize it, but they TEACH the horse to bump, push and demand.
Do you REALLY think a horse is going to work better for you, if it's trained by force? Do you REALLY think that your horse is going to be fixed by being knocked around? That is about the worst possible thing you could do with THAT ANIMAL.
The animal may wind up subservient (and also leap in terror if you move your hand near its face). And as long as it's tied up or you have the hand on the reins it might obey, but the SECOND it gets loose from you it is NOT going to do a single thing for you because all it wants to do is get the heck away from you. And it's far more likely to cause an accident by being so afraid of you that every time you sneeze it leaps away.
Just because someone is Amish, doesn't automatically make them a good horse trainer. Just because someone is Amish, doesn't make them decent with animals. Amish people are not different from other people when it comes to handling horses. Very, VERY few people of any group are actually good horse trainers, get good results, and don't create more problems than they solve. And very very few trainers, even of the good ones, are going to get the best out of YOUR horse, because yours is not the usual dull jughead most local trainers specialize in.
Even the best Amish trainers tend to be rather rough - I find it hard to believe you would be happy with the results or find the animal much more controllable or enjoyable - probably a lot less.
They train like most farmers trained draft horses a hundred or so years ago, and believe you me, most of that sort of training, would destroy your horse in particular, not make it better.
I've seen them do some pretty bad things - barbed wire wrapped around a bit for a scared horse that spooked now and again, a horse put in a sharp bit and the reins sawed at with all an adult man's strength, until blood poured out of the animal's mouth('NOW he ain't a gonna pull no more'). The worst one I saw was the horse that was hit in the head with a hammer repeatedly, when it didn't come when it was called.
Your horse can be friendly and cooperative WITHOUT being overly pushy and obnoxious. Being friendly in a reasonable and safe way, won't interfere with the horse working for you. Absolutely the opposite.
My horses are treated with firm patience. They're corrected when they do wrong. When they are afraid, we work it out, approaching an object and being rewarded for their efforts. They are not barging into me, demanding treats, and both of them have saved my rear, many, many times. If I fall off, I call them and they come back - a horse trained rough will NOT.
If you train a horse with force, you ALWAYS have to use force, and there is no relationship, just wary obedience until it gets away from you. When you train a horse with patience, firmness and do it in a way he actually understands and learns something from, you have a partner.
