Ok well I have a 16 year old appaloosa gelding, he hasnt been worked in 2 years. My saddle fits, but he doesnt like the bit. I'm going to change that tomorrow. I set him up and ask and he just rushes into a HUGE trot. I stop and try it all over again, he still does the same thing. I just ordered a crop, so maybe that will help. Could he just not have the mucleling to canter yet?
