no it is not legal but most types of snaffle are accepted and when you get to elementry you can use a double bridle but if you do you must wear spurs! and pelhams are never alowed in dressage but yeh i would ask your riding instructor or even look it up on the internet about what bit is dressage legal.

Hope u find the right bit

not sure really, if you look up the rules and regulations on google for dressage it lists what you can and cant wear, I know we had to change my daughter's pony's wickie snaffle to a normal eggbert snaffle just because it had a 'low port' and that was in a basic walk and trot test!!!!
