My instructor says my horse leans on the bit and I ought to get a bubble bit, not because she is strong but to stop her leaning. I dont know what one is
Yep is a dutch gag, also known as a belgian gag/continental gag/three-ring gag/three-ring snaffle etc. (don't know why it has so many names!) Looks like this:
A dutch gag is quite a lot stronger than a french link snaffle. You could try a hanging cheek which isn't as strong as a dutch gag, or maybe a waterford to stop her leaning.
ETA - is her snaffle eggbutt or loose ring? My mare leans with an eggbutt but not with a loose ring.
I have a hanging cheek snaffle as well and she does the same in that. I dont really want to put her in a stronger bit if I dont need to. I asked about the flexi-reins because I have just read their ad and it says 'largely eliminates leaning on the bit and also head shaking' which is another of her little habits
To stop her leaning try a Loose Ring waterford snaffle, a French Link snaffle or a Myler Comfort snaffle. There is no way I would use a Dutch gag for a horse that leans.
If you do try a waterford they say you need a bit that is 1/2 inch bigger than your normal bit size.So if you use a 5 inch bit a waterford needs to be 5.5 inch.
Have you tried her in a loose ring? You might find it makes a difference, it did with Shadow. I can't comment on the flexi-reins as I haven't used them, but they sound like they could help.
Have't tried a loose ring but will do so. I really feel uncomfortable trying stronger bits (although my instructor does say I have good hands and wouldnt be bad to her!)
Just to update you have eventually got in to paypal and bought a loose ring waterford snaffle half an inch bigger than her usual bit. I will let you know how we get on with it.
I have to say that I think you are showing an alarming lack of faith in your instructors opinion, & I wonder if perhaps you need to think about changing, as confidence what your instructor tells you really important. (Having said that if any of my pupils bypassed my advice in this manner the changing instructor question wouldn't be an issue........!!!).
There is nothing wrong with any of the advice given on here, but perhaps you should have discussed the matter & your concerns re the dutch gag in more depth with your instructor.
Remember there's no such thing as a severe bit, only severe hands, so as your instructor tells you that your hands are good that shouldn't be a problem.
I think your instructor would be talking about a Waterford, I have heard some people call it a bubble bit.
You would need a waterford snaffle, I always thought a bradoon was the snaffle part in a double bridle and I did'nt know you could get a waterford one!!!!!
