My girl developed head tossing in her french link snaffle so I thought I would try a Myler on her and see how she liked it before spending that much money.
I'm not sure if she likes it or not. She's not chucking her head around, at least... but her mouth has gone very hard. From soft and light in her fat french link snaffle to heavy in the Myler. Literally overnight.
The bit in question is a level 1 Myler comfort snaffle with no rein hooks. I need a dressage legal bit and it's one of the two Myler options that are allowed.
At this stage I'm assuming either she doesn't like how thin it is [it's the thinnest bit I've put on her] or she doesn't understand the different action. She's been exclusively in a french link for quite a while now and was mouthed in a normal single jointed snaffle so it's possible the action of the Myler confuses her. She has been ridden in a mullen mouth snaffle and did okay in that but was also heavy in it and because there was no independent side movement she found the muddy signals to be hard to decipher. She's a very sensitive horse and easily confused.
Other than being heavy in the hand she was very well-behaved aside from one minor issue which I believe is more to do with saddle fit [in the process of rectifying this].
I RIDE ENGLISH and this horse is dressage trained. I am quite certain I was not pulling on her. She wasn't pulling on me either, she was just a lot heavier than I'm used to. Nearly as heavy as my old horse was.
