I am actually looking for possibly a website or article that might have information on handling horses, and how to teach them to respect you. I do not have an issue (usually)

with this, but there is someone in our barn that just got a new horse. The horse is too much for him, as this person is very green.. horse has been neglected and is about 200 lbs under weight, about 16.2 hands TB. He will not listen to me when I make suggestions on how to handle the horse but he likes to read all about horses so I was hoping maybe someone could point me in a direction that he could read for himself what he should be doing. Right now, he lets the horse walk all over him- he says "Oh he's my boy, he loves me, he trusts me, he wouldnt hurt me".. but there is nothing being done to encourage any respect from the horse. If the horse wants to stand there and be held, then great, but if the horse tries to pull his head away from him.. he just lets him go. "Ok boy, you can go now, I know you don't want to stay here." He was reluctant to be wormed- and he said "oh don't worm him today, he's in a bad mood. He doesnt want to do it". These are literal quotes from him.. I try to explain to him how it works in the horse's world with respect etc. He doesnt listen, I know nothing. As frustrating as that is, I am just trying to help. This horse is large, and once he gets the weight back on him could be very dangerous if he is allowed to do whatever he "wants" to do. Any suggestions???
