Derin I hope you don't put those arabs in stocks, that would be a disaster. I have found that Arabs can get very nervous about things very quickly. You need a gentle approach and quite enviroment. More importantly the owner and trainer need to know what they are doing with this breed. Once they trust you they are generaly very good to work on.
Draft horses accept the stocks because they are a pretty docile.
I need names of companies who manufactors shoeing stocks. I work for several arab horse farms and some of them are hard to handle and one of the owners offered to buy stocks for her farm if I could find some. I have a couple of months to get them ready for the show ring. If I had to put a horse in a stock to shoe it. Well I just would refuse.
