Now I cannot for the life of me get him to canter and when I do he will not stay at the canter. He canters fine in the round pen. I told the girl I bought him from how he'd been acting and she thinks it's really weird. She said he's never been a lazy horse. I've had a friend get on him and he did the same thing to her.
I'm beginning to lose patience. I get really discouraged and feel like a bad rider, but when I get on other horses they canter for me so I know it isn't me. He hasn't shown any signs of soreness or lameness either.
