Here’s a question for you two. We are introducing my younger gelding to the double bridle, he is schooling 4th level now. If I so much as put even the slightest bit of pressure on the curb (right side only) he immediately goes rein lame! I’m pretty good with a double bridle, so my trainer tried and she had the same problem. She wants to wait for my clinician to come and figure it out, which I agree with. I would like your feedback on this, pretty, pretty please!!! I’ll say nice things about you!
his contact on the snaffle bit is maybe not even, and it is only noticeable when he hits the curb.
go back and correct that so he is even behind, get both hind legs to come thru better.
also think he could be getting behind the bit and you just need to push him to the bit more with your legs. i’ve seen that happen a lot when the double bridle goes on. but be wise and ponder if maybe he just lacks the strength and steadiness of contact still to go onto the double bridle (by this i mean a horse needs to be strong to go on the bit in the double bridle, it takes more strength in him and the rider for sure), it is not such an easy thing for the horse.
he can also be crooked and made more crooked in the double bridle.
the double bridle always magnifies any problems in the training, so it can be there is something you need to go back and fix, such as making the hind legs carry the same amount and making the suppleness in the poll and jaw, and making the shoulders not go to the outside, in other words making the horse more straight and ‘‘standing up on his legs’’ with the same amount of weight on each leg. think about using position fore if you need to make straight and watch the outside aids when making any circular track, bring the shoulder around with the outside aids.
in general i’d suggest you do like most of us here do and ride with the curb reins tied up on his neck for about 6 months, too only school 1-2 x a week in the double (so that six months isn’t really that many rides in the double bridle). after some months you take up the curb reins but leave them loose without any pressure. only later you take up the rein, and then use it very sparingly, and on the other rides confirm very much the forward and a good contact and fix any issues the double bridle brought up.
also check the fit of the bits. the mouth piece of the curb may be too thick for his mouth; at least that’s common in my area.
a lot of people start putting on the double bridle earlier than you, but don’t pick up the curb rein for ages, that way the horse can get used to the bridle and bit with plenty of time and no difficulty. but you don’t have to show at 4th level in the double bridle so you have time now too anyway.
alot of horses will have it on for a long time with the curb reins tied up so that they get comfortable with it easily over a long period of time.
