I'm in year nine now - I think I'll be limited with time and money to look after him when I get to year 11 and 12 (because of what I want to study), but I want to keep him, so I'm thinking of breaking him in and leasing him out (he's way to small for me to ride anyway).
He's never been 'officially' broken in, but he accepts riders and has worn the bridle and bit. Just walking, I ride him casually bareback sometimes, though he doesn't fully undestand the aids and he's never had a saddle on. He can be lunged. He sometimes has a bad attitude, because I've let him get away with things before.
I've only had him since January 2007 (my first horse).
Is this something I can work on my self or something I should get a trainer to do? How long will it take?
