do you mean the cip cap?? Sylvia teaches left and rights by doing spins - which is actually what I have taught as well - but I have never really used it on the agility field because I know I will mess up and spend too long thinking about which is which and which way my dog is facing
I do the cip cap out on walks for a bit of fun but both my dogs wrap jumps really tightly anyways so I havent taught it on the agility field either

Sorry, I should have specified obedience left turns rather than agility

Slyvia dosent really do obedience? you mean the front paws on the target thing??
I do that, it is really clever and great for getting dogs to understand their bodies

Yes, that's the one . Been doing it with Jago and it's amazing how quickly he picked it up, I swear he's telepathic. Just have to build it up now so he's using a smaller target and then with no target. Great trick!
