What are your best suggestions to deal with a horse that roots on the bit? Please keep in mind that this horse has had extensive body work (Regular professional massage, chiro, PEMF, Acupuncture, regular dental work, laser therapy...) basically everything I can get my hands on and this issue is long standing and on going. His saddle fits extremely well (ive been through that journey already), his feet are done every month, he is always sound and happy (KNOCK ON WOOD!). I ride him in a plain snaffle generally. I would like to try a myler bit but have no yet. The only thing I have found that he doesn't root in is a correction bit but I don't want to ride him in one. But I can't deny it was nice for my arms and hands to not be dealing with him rooting constantly. Training doesn't really help. I have NOT tried a bosal. I have one but I haven't used it yet. Thoughts?
