My daughter has a little pony, 14 hands or so. She is gentle and sweet. The problem is she drops her head to the ground to eat and graze. She literraly pulls the reins right out of my 39 pound 5 year olds hands. Once the reins dropped down her neck, she stepped on them, popped her head up and began trotting away, growing my daughters head, helmeted THANK GOD, into a tree before coming to a stop when she regained the reins and spun her in a circle to get her to stop. This is so dangerous. I wonder if we need a better bit, she usually rides in a hackamore or curb bit. The worry is, my daughter is learning and can be inconsistent with her hands. I don't want her hurting or frustrating her horse, but I want her safe as well. She rides English, is there a way to tie her head up while still giving her the ability to direct her?
