oH, another trick i like, is, in my neighborhood, i've pretty much got Buddy to stop at each and every corner. Now he does it without being told. He almost always will look up at my face while he does this, too, without being asked to.
(Which is yet another useful cue, is "look at me", to get his att'n onto me.)
We have one busy-ish street in my neighborhood, and i doubt, if Buddy ever got free he'd reflexively stop at the corner, but he sure does when he is with me, he gets "A+" for always remembering, especially at that corner. (i always leash him for that area anyway, of course). This is nonverbal, no cue given by now, he has just memorized this habit after so long. He stops on his own, at each corner in our neighborhood, til i say "okay" or "cross", depending, and then he moves fwd.
I'm pretty sure Buddy only does this from memorization, ("this is that spot i get treats sometimes if i stop, right HERE.") not from understanding the concept of a corner. He does not stop in strange neighborhoods at those corners.
I did NOT train a sit with that stop, cuz, Buddy has very very long fur on his haunches, and he really just doens't need all the snow, mud and rain etc etc, getting all on that fur if he doesn't have to. But he does stop, look up at me, and wait til i say "cross". Which is another cue he understands, is "cross"-------- he knows we are going to cross the street.
Now that one, "cross", he does generalize to any street, anywhere, but the corner thing, not so much.
Hard to explain, but most of our streets are curvey, and i've got a few spots, where i've got Buddy to understand, at those spots, i want him right beside me. (cuz i can not see what is around the corner, a car, a dog he won't like, a bunny, a deer, etc) buddy has also memorized those spots and usually without my asking, will now mostly automatically fall into a heel for those spots.
