Here’s the beginning of jazz up & down!
First, I’m just walking - empty, energy level 0 - with his super high value toy to the yard. He used to spin in circles, jump, pull, tug, try to take the toy, nearly knock me over, etc., while I tried to do this. But now he picks up on my energy level and, while still expressing he wants the toy, understands we’re not playing yet. Eventually, he sits down politely.
Then I do the jazz up by suddenly exploding my energy level to like, idk, 7? 8? It could be higher, but man it’s fuckin’ hot out.
Then I suddenly bring us back down to a 0 by asking for a down. He calmly lays there, not even a whine.
I reward him with the Wubba in the end by tossing it into the yard.
This was the first round. The follow up rounds I mostly varied the reward by throwing it and then releasing him with a ‘free’ command instead. I also jazzed him up a little bit longer. Oh annnnd put myself at an energy level 0 BUT waving the toy around.. he read the energy instead of the toy, stayed sitting/laying!
