I've been considering spur training my horse. He's already in the works of backing up when I apply pressure with both spurs and say "back". He is learning/knows not to move when pressure is applied until I make a sound. (Aka spur+cluck for walk, spur+double cluck=jog, spur+kiss=lope) So, two spurs + "back" = back.
What I would like to be able to do is apply pressure with one spur (I only use two for backing up), and have him round up (which he does already) and slow down. He does slow down slightly but I would like it to be more of my speed control button.
My question is, how would I go about achieving this? I could and will ask my trainer next time I go for a lesson, but money is tight at the moment and I honestly don't know when the next time I'll get to go is. So, for all you people out there that know about spur training, help me out?
Also, I have been considering teaching him to spur stop, but I'm not sure if this is really necessary or beneficial. I've heard people say they love it, but then have also heard people that hate it. What are the benefits of it? Should I even bother? He stops now with a simple "whoa".
