When I first got my horse (4 months ago).. she let me put the bit into her mouth super easily. But a little while after, she started being resistent to letting the bit be put in her mouth. Her bit is a low port curb bit. Now, when I take off her halter to put on her bridle, she yawns and yawns alot! Like she is stretching her mouth to prepare for it or something. When the bit is in her mouth, there are about 3 or 4 wrinkles. I keep a fairly loose rein when riding her, and don't pull on her much.
Do you think the bit might be too high in her mouth?
I was also thinking, I am going to be entering in a couple gymkhanas this summer with my friend, and I was thinking it would be better to ride with a snaffle bit for barrel racing and stuff.
I am going to be showing in reining as well, and I will need to use that bit..
PS: When I made the length of the headstall longer, it seemed like the bit was hanging and not really doing its job, so I can't change the hole of the bridle.
