I recently bought this wonderful, sweet quarter horse filly. To pick up her hooves is tough. Her front hooves, she will let me pick up, but her backs, she won't. The process of me trying to do this is I get up near her back leg, I slide my hand down, I pick it up, then she'll start using her free legs and move to the side I'm not on, she starts kicking her hoof out of my hand. Any help?
