hey katie! The word we use 2 get them 2 change directions is reverse and I just walk a couple strides ahead of her instead of the usual following behind the girth or hind end... then say reverse or just move that way and if he tries 2 pass you then be stern and get in front of him &make him go the opposite direction just so he'll know that's what ur asking. It'll be a little different at first, even if he has learned it before and hasn't done it 4 a while...lucy gets like that if I don't lunge for a while.
The canter thing..it depends on the size of the round pen or he could just be trying 2 stay out of the canter like my horse sometimes does, just lazy or maybe a little unbalanced at it..remember, they get frustrated just like we do! Lol. What I did to train her was every command you say in a different tone of voice & a dif way (if you want 2 voice train 2) like walk is "waaaallllkkk" drawn out 2 get them 2 slow down, trot is "tur-rot" in a more happy tone.. say his name, then say trot, try trot again n a more stern voice, and then trot w/ whip added, give him a chance before you get the whip after him &u'd be suprised how soon they learn the words.. same way with canter, I say it "caaann-TUR" & I usually have 2 use the whip on this..lol. Then I stay with her to keep her going and use clicking sounds and whip if necessary....dont 4get 2 add good boy and praise him! :) to get him 2 walk, say walk and stop where you are so he knows its ok for him to slow down... pretend there is an air bubble between you and ur pushing it at him by followin him 2 make him faster and when you stop the pressure is released and he can slow. If he stops click and say walk, just spend A LOT A LOT of time doing the basics then start adding ground poles, then x's.. it takes a while for them to get used to it and you want him to listen 2 you first before he's worried about what he's stepping over or tryin 2 go around...lol.
Srry it's so long but it woulda taken me 4ever 2 tell ya all this tomorrow...haha
Just let me kno if you have any ?'s
