Thanks, I did find the post done by JDI and read some interesting things in there. It seems to just depend on the horse like most things. My horse is a 21 year old Arabian that was given to me free because she "wouldn't take a bit" In the past 5 months that I have been working with her, she does well with a bit but tosses her head quite a bit when we canter (but mostly just when I put any pressure at all on the reins to ask to slow down) as well as displays other signs that are labeled under Facial Neuralgia on bitlessbridle.com. I'm not sure if this will work out like I hope it does as she also does not like to be ridden in a hackamore or sidepull. I'm afraid that with her age, I do not know what all types of training she has had and just figured we could give this a try since I can return it if it doesn't work out. I'm almost out of ideas of how to fix her problems. I love her dearly and would hate to have to give up on her as I can't afford a "pasture ornament". If anyone has other suggestions as well, please let me know and if this doesn't work I will try those too!!
