The first thing we tried was a regular ring snaffle bit. As soon as he saw it he started tossing his head. We got it in place and the head tossing got worse. He was very agitated so we removed the bit.
Next up was his halter, which he did surprisingly well in he just wouldn't stop.
Then, I tried a Dr. Cook's bitless bridle. More head tossing. More agitation. Made for a very frustrated horse.
So now I have figured out that the original snaffle we tried him in was too small for him. It was a 5" and he needs a 6 1/2". Could the size be what was causing his distress? Would it be worth my while to purchase another snaffle in the larger size, or would I be better off exploring a different type of bit all together?
I also have a mechanical hackamore I can try. But the shanks are very, very long (8.5") and it scares me a bit since I'm a beginner. He does not shake his head when I put the hackamore on though.
Anyone have thoughts? I have been told to try a snaffle bit with shanks. Is that an Argentine snaffle or a tom thumb? I can't quite figure out the difference between the two.
I know that's a ton of questions but I'd really appreciate any help and information!
