Yes, I know. Bruce is the same but try a pair of impuls spurs and a deep seet. Impulse spurs are great (you can find them on equiport)
Failing that, and i havent seen your horse jump, but a rope noseband and a french link with sides (you know, bits that stick up either side....god I am useless) works a treat. Maybe the gag has got too much poll pressure which is why he is tucking his head in.
Usually if they are overbent it means that you are on their mouths a bit too much and not using enough leg. You are only diddy so I am surprised he knows your sitting on him! LOL!
Hehe yes being so small does have its setbacks occasionally! I do try and use my leg but he reacts very sharply to it, though i know i should support him more with my outside leg when i turn and would feel this would be easier if he wasnt so tucked in
I think you're right about the poll pressure causing him to tuck his head in, at first this is what he needed but as he has progressed i think now he needs less pressure on his poll
Will ask my trainers what they think
Thank you so much for your advice
How does he behave doing pole work?? My horse sounds a lot like yours does, he schools lovely on the flat in a snaffle but gets quite strong and fixes his neck when he's jumping. I tried lots and lots of various bits and he'd go fine for a while in them and then get wise to how to avoid the action of them. I wanted to jump him in a snaffle so just did loads of canter poles trying to keep him as soft and calm as possible and then move up to little cross poles and then a bit bigger until he was going remaining soft going around a course of fences. You could also use spurs on him or a schooling whip if he's not listening to your leg. If you keep the hindquaters engaged it's harder for him to fall onto his forehand and fix through his body and neck, making it easier for you to steer him.
Gives you more options. When he's soft you use more top ('snafflely type') rein. If e starts to get strong you use more lower ('curby type') rein. You have the option of putting the lower rein on the middle or lowest ring. You do need to know how to ride with two reins & use them independently, but I'm sure that shouldn't be a problem for you.
Advice re canter poles & more leg is worth taking on board as well.
i agree with DD, i think you need to concentrate more on his flat work and getting him to relax in his mouth and to take the contact more and to lift his shoulder up and get him more through from behind. IMO changing bits isnt going to stop him falling out through his shoulder, or get him to become softer in his mouth. All this comes through schooling. Perhaps give him some time off the jumping and concentrate on your flat work with added pole work for a few weeks. Raised trotting poles are great for lifting off the forehand and getting the shoulder up and straight. Also lots of leg yielding and shoulder fore.
im sure you can sort this problem without changing his bit, he is still only young. (and dont think im saying this to have a go at you, as im not, im saying this to be helpful) x
I know you say that this problem is only when jumping. cant you put up a mini course of tiny (like 1' high) jumps and school around them - in your flatwork tack, and only pop over the jumps when he is paying absolutely no attention to them, and again then school around them. so basically just incorporating the action of jumping into your regular schooling and see how he progresses.
For a youngster like this, and really any horse, a stronger bit is not really an answer. As already mentioned by other people schooling is the best option. If you have a dutch gag on him as a 5 year old what is he going to be in when he is older? That bit made of barbed wire and spoons?
