I own a 4yr old American Saddlebred that im currently training to become a jumper. I ride in a regular snaffle. He normally gives me a hard time bridling. I have discussed the bridling issue with the vet and he thinks it may be becuse his canine and wolf teeth have not come in yet. I was riding on sunday and he was relaxed and going well in a frame on loose reins. Well I think he saw a rabbit and tensed up and started and take off, so I pulled him up. Not sure if I did it too fast and took him off gaurd, but he reared up and flipped over ontop of me. Unfortuantley I was in a western saddle so the horn hit my leg. Thank god it's not broken. Well he has given me trouble bridling since I got him and was wondering if he would be more comfortable in a Hackamore. I've been told its harsher than a bit. But im not sure what to believe. Any suggestions on what kind of bit I should be using?
