I'm working on my front porch with 2 steps. I like working there because the dog has to really move to go forward. There is no cue. Presentation of the db will be the only cue. I either remove it by putting it on my shoulder or toss a treat to reset her, which builds forward movement toward the db. High rate of reinforcement builds drive to get it in her mouth. When I lift it over my head she's jumping up to get it, that's what I want.
Early in the video Pais gets clicked for turning her head to the right along with the "pull," she repeats the turn, so I tossed a treat to her left to reset and kind of undo the right turn. She steps back 3 times, so I lower criteria and click for a shorter period of time before she gets a chance to take a step back again. Then raise the time period again since she didn't back up.
Shaping this isn't a gradual increase in criteria. It's flip flopping. Sometimes shorter, sometimes longer - allowing the dog to learn to wait for the click before dropping the db, but keeping the rate of reinforcement high.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
