I ride Ginger in a Dr Cooks. He doesn't have any issues being bitted so I'd never really thought about bitless until several years ago when we were waiting for the dentist to come and he seemed a bit uncomfortable in his bit. I decided he should probably not wear his bit again until the dentist had been, but didn't want to stop riding so just as an experiment I tried riding him in the arena in just a head collar. He was amazing! He is very responsive to seat and leg aids and doesn't need a lot of rein anyway, and he didn't go any differently in just a headcollar! I also tried him in a rope halter with the same result.
I borrowed a friend's Dr Cook bridle so I could try hacking out bitless and he was fantastic in it- very responsive and relaxed. My hubby bought me my own Dr Cooks for my birthday a few weeks later and we haven't looked back. We have done allsorts in it- hacked, schooled, jumped, ridden on the beach, had days out. I love it :smile:
I would say he goes as well bitless as he does bitted. If anything he can be slightly heavier in my hand bitless, but some half halts resolves that. I do still school him in a bit, mainly because of this, but also because I still want him to be used to a bit if I decide to start doing any dressage again. I haven't competed him in it as unfortunately it's not allowed for dressage.
We use the bitless more often than not though. He still goes well bitted, but I don't see the point in putting a bit of metal in his mouth if I don't need to.
