So, I recently purchased a 13y/o cob type. He is the sweetest chappy in the world. He has a brilliant attitude to his work and works beautifully through walk and trot but unfortunately when it comes to the canter, his days of being used by travellers as a trotting pony shine through and his canter is just awful. He really struggles, it can sometimes take two or three circles of asking for him to even break out of trot at all and when he does he just runs straight through. I have tried a few different exercises with him and he seems to struggle just as much with each one to the next. Does anybody have any suggestions of things I can try?
