Leave and wait (stay)
Releasing what's in the mouth.
You may be surprised that sit and heel is not on my list. Ask me why!
And although coming when called is important, it's not the first behavior I teach. You can ask me why with that, too!
My clients get all that info and more, For example why, depending on the dog, teaching her to nose-target the hand and backing up on cue, is super helpful.
