She's a really sweet girl and learns extremely quickly, but she is STRONG. Her breaks are quite good (she's very responsive to seat and voice) but she pulls a lot, especially out of the ring. Normally, I am not a fan of using stronger bits to control a horse as I understand it's more of a behavioral issue, but because of her size, I'd like to get something with a little more "bite" so she understands she needs to stop fighting with me. She's currently in a slow twist snaffle. Any advice on what I should try? Ideally, I'd like something (legal) that she can eventually use in dressage, but obviously have no problem using something stronger XC. (And I am aware that she can't use a twisted bit for dressage as well.) All of our horses go in snaffles or Dr. Bristols, so I'm not sure what would be appropriate for Bella.
We're going to start some major pole work this week, as well as lots and lots of circles and transitions to make sure she's listening to me. It'd just be nice if we could do that without getting my arms ripped out
And just because she's adorable, here's a picture. Please excuse her extreme fatness; she's a work in progress.
