I've got a gorgeous 13.2 hh pony who I love very much. I am working on retraining her, and she does have some trust issues*. I would like to try a hackamore with her, but I have very little knowledge as to whether there's any particular sizing that I need to worry about etc. I'd like to get a hackamore off of statelinetack.com as I've got a gift card there... but they may or may not have anything suitable for her. The two I'm looking at are:
I am fairly clueless as to whether either would be suitable for my pony. I know pretty well how they work, but I'm wondering if things like shank length and whether or not there's a chain under the chin will make a huge difference.
*To get into more detail: Her previous rider kept a near constant death-grip on the reins. When she started rearing in protest, she was offered for sale. I bought her and have never had difficulty with her rearing because of my natural tendency to be far softer on the reins, but she is stiff and unwilling to give on the left side in particular and she rushes the jumps because she fears that the rider will lock down on her head and hamper her ability to get over the jump.
