Any advice, please, on which bit (snaffle, not curb) can be used to prevent horse from putting tongue over it. She has rather small tongue. French snaffle doesn't seem to be working well - she moves it over all the time. I was thinking about mullen mouth (as I'm looknig for something VERY mild), however my concern is it's not the best one to teach horse to bend. Any suggestions?
I have a growing 16.1-16.2 mare that uses a 4 & 3/4 inch bit. She has a slender and refined head, therefore a small mouth. She would literally chew on the bit when I assumed she needed at least a 5 inch bit (our first few rides). I later discovered just how tiny her mouth was for her size. Generally, the bridle or bit needs to be readjusted in size when the tongue in coming over the bit.
We have used a Full Cheek Snaffle to keep that from happening. They are great because it keeps the bit from running through the mouth, There are different types of severities, and they are great in making the horse become supple and bend and flex. I train western pleasure horses and I use the same bit on my 2 yr olds who have that baby doll head, all the way up to my finished show horses. Hope this helps
I have found with horses like that. A nice thick french/eggbutt snaffle with a hanoverian nose band works wonders rather than using anything harsher. Maybe you could even try a training bit or sweet iron bit if she puts her tongue over it because she is playing, bored or uncomfortable.
The bit I'd recommend for any kind of problem mouth is a KK bit. They're not cheap ($100) but for me it was the last bit I ever bought for my gelding, and believe me I went through a lot of bits. They are balanced and just sit on the mouth correctly, and also are made of a metal that horses like. KK is a brand by the way. They make many kinds of bits. I'd recommend talking to a local tack store about which kind.
I've never had good luck with a mullen mouth. Tends to make them lay on the bit.
Before you go try different bits and nosebands, try moving the bit up in her mouth. If that doesn't work try a flash to keep her mouth shut as it's harder for a horse to get their tounge over the bit if their mouth is shut.
