I have been teaching my 3 month old puppy to "leave it" and to wait for things like food, toys ect. I watched a few youtube videos and one way I saw that looked involved touching the dog to release it. My puppy picked up on it quickly she is almost flawless inside, and sort of ok outside with all the distractions and things to eat out of the grass. When I release the dog I touch her on the top on her neck and say "OK" at which point she can go to whatever she was patiently waiting for. My question is how can I get her to just cue off the release command instead of the touch?
