a little more on the horses--- used Amish horses tend to have high rates of ringbone (high and low) bowed tendons and other leg problems... and they tend to die at 10 or so.....
Amish trainers use the same methods EVERYONE used back in the day...Their using horses are dead broke to task and very reliable... Good trainers use a little of the 'horsewisperer' mumbo-jumbo and a little bit of firm hand.... a must if you plan to use a 1000 pound critter to pull the wife and kids in traffic.
The pathology is very similar to ALL horses prior to 1920 or so... WE all have an easy life today.
