That depends...The filly who isn't changing, I pick her up and slow her down (She rushes when she crossfires) and she then switches her hind. If she actually changes, instead of crossfiring, she doesn't rush at all.
The colt, I roll my spur or break him to the trot/walk if I have to. Whatever I have to do to correct it. Once they do get it, I go ahead and relax.
I did get the colt to change today though. He crossfired the first time, then I kinda just screwed around with it and I found by over-exaggerating my inside rein he would lift up and change. I've spent so long trying to get his hip soft that if I mess with that too much now he gets irritated. He's a very kinda horse so I only do what is necessary without picking on him.
The filly however, we got one change to the right and never did get changed to the left. She is terribly stiff. I always have to spend extra time bending her, and even after that I don't think she's ever going to be as flexible as some.
The two colts that are already changing have proved to be wonderful. I have a roan filly and a bay filly, both will change on the straight if I asked them too.
I agree with you guys that colts shouldn't have deadlines - But in the cowhorse industry they have to be ready to go at a young age. It shouldn't take this long to teach a change, imo, and I can see how the boss is getting frustrated but I also think that these horses in particular are just going to be difficult. They've had more cow work than the other two, and less dry work, so they aren't quite as refined which is where I think the problem lies...
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
