I have a question. Maybe it's the broken mouthpiece?
When I rode her in a curb bit (just kind of for the heck of it) she did well. A little confused because she's used to more solid contact and not so much on the loose rein but she did well. And it did not
bruise her mouth, whereas every single snaffle I have tried does. And it's not because she's pulling. She's always a little strong but there was no yanking or sawing on her mouth, nothing that should cause bruising.
The curb looks like this:
There are only two things I can think of that is different between this and the snaffles that would make a difference in her mouth bruising. The thickness isn't a factor because my snaffles of all different thickness didn't work. There's 1) the fact it uses leverage and not the direct pressure like the snaffle (though it still puts pressure on the bars?) and 2) it's not a broken mouthpiece. I think I can find out which one it is by using a Tom Thumb which she was ridden in before. If it begins to irritate her, it's probably the broken mouthpiece because in all other respects a Tom Thumb isn't any different from the curb I used.
(she still hasn't had her teeth done but isn't having any issues with her mouth other than bitting. Our truck had issues and has been in the shop for weeks)
My main questions are, how might the curb be not
hurting her in comparison the the snaffle? How would the broken mouthpiece be possibly hurting her but not the mullen? Do those mouthpieces affect the teeth differently?
I have not tried a mullen mouth snaffle, but I want to. I'm just not sure how well she'll go in it. I could maybe get a type like a Myler that moves a little in the middle for clearer communication?
