A little bit of her history: I have a 2 year old standard bred TWH cross filly that I bought several months ago. She had already been ridden quite a bit by the people I bought her from, but I thought she needed to grow more before I started riding her. So I gave her several months off, and recently started riding again. However, after getting some advice in this forum, I have decided to give her more time before extensive riding and have started focusing on ground work stuff. She has a great attitude, very laid back, calm and ready to learn.
The problem: While I was riding her, she constantly "played" with her bit. I have a snaffle bit and another bit that was suggested by some other gaited horse riders. I think it is called a pleasure horse bit with a 4" shank? She doesn't do very good with either bit, and gets pretty frustrated with it being in her mouth. I thought this would be a good thing to figure out to prepare for riding next year, something that I can work on from the ground. What should I do? Is it the type of bit, or is it her simply not accepting it?
