A Thoroughbred gelding named Dream Catcher that I use for lessons has a tendancy to always paw with his front hooves, and pick up his back legs to try and kick while he is being groomed. I really don't think it's a health problem that causes grooming to hurt him, but rather behavioral issues. This is clearly not safe, and annoying because I'm constantly stopping. So, is there anything I can do to maybe stop this or prevent him from keeping it up? Thanks for any help!
