I need to teach that to mine. I started with Miller once and he will still come and touch my hand if I hold it out. I wasn't doing it quite the way you describe which sounds like a better way. I"ll have to try that! I've been looking for some things to teach that could be taught in the house since it's too hot to go outside.
Why don't people realized that flexible leads have a lock? The dogs don't have to be 15 ft from you. It's ridiculous. I see people all the time in my neighborhood walking along by the curb with their dog in the middle of the street I guess they think if he's on a leash that's all that matters. Idiots. Reel him in and lock the leash so he's out of the street.
