Horse Questions (Would love answered so I can work with my Horse today)?

i don't have a horse, but i have been riding for about 8-9 years and I have been in various shows and i try to spend any time i can at the barn. I would suggest working in circles. is he allowed to walk trot and canter? if he is, then if you are allowed to put a saddle on him, just stick a saddle or a bareback pad on him so he doesn't get out of shape and then have him lunge in circles. it helps sometimes with training. you can also try to play "games" with him. think of something that will be a bit challenging. i would suggest maybe trying a HORSE soccer ball, and maybe having him kick it around. you can also try number 4. try to expose him to water bottles and umbrellas and weird things that you wouldn't normally think of. you would be supprisd what horses are scared of. I once rode a haflinger who was scared of a saddle. see, she was fine when you were holding the saddle and when it was on her back, but when she passed the gate and their was a saddle that she saw outside on a rack(That's where they put the mwhen i needed to clean them) she would freak out and stop dead in her tracks. she was pretty crazy. but anyway, just try random things, but don't overwork him because his leg will get worse. i would suggest calling your vet for more ideas and keep those nails out of the barn!!
