I just bought a new horse that has not been rode for awhile. The guy I bought the horse from always used a hackamore and when he rode the horse he would let him go where ever the horse wanted to go and not guide him. Now I have him I am having a hard time getting him to do what I want him to do. Should I stay with the hackamore or should I go to a bit? I am so afraid that I will hurt his nose as I have never rode with a hackamore before, I always use a bit.
