If I put both legs on my horse when it is standing still, I want it to move forward. How many cues do you need to make your horse go forward? Do you put your legs on, say “walk on” and push forward with your seat? Why do you need 3 cues to get one thing happening? To establish a cue you will need to give one cue at a time. Less is better. It will make for a far more refined communication system.
I challenge you on your next ride to see how many cues you need to get one thing done.
It also works the other way around. If you horse is running away for example, how will you stop it? Can you only stop your horse from going too fast by pulling its reins? I would like my horses to stop on my seat, or on my voice, or when picking up rein pressure or in case of emergency I can do a one rein stop.
I have taught my horse more than one cue for the same result. This means I have established a range of cues, which I can use in case I need them. Most likely in an event where my horse is in a new environment, nervous, in a show situation or just not willing. So instead of having only one big red button on my plane (you will be screwed if that one doesn’t work!), I have a whole cockpit full of buttons and levers.
Teach your horse one cue at a time. This way you will build up a large vocabulary so that later on you can start putting more than one cue together to make sentences.
