Your dog is now reliably targeting the dresser drawer, and so far,
you haven't opened your mouth. The next step is to put the behaviour
on cue, which means that the dog becomes able to perform the behaviour
Choose a verbal cue (command) such as 'Touch it'. The next time
the dog targets the dresser drawer correctly, say 'Touch it' just
as the dog's nose touches the drawer, and c/t.
Repeat this a few times, and then gradually start saying 'Touch
it' earlier and earlier. After a few repetitions, you will notice
the dog starting to target the dresser drawer in response to your
saying 'Touch it'. When you reach this point, start counting again
- count out 10 treats and say 'Touch it' 10 times. C/t for every
time the dog responds by targeting the dresser drawer.
Repeat this step until you get 9 out of 10 successes.
Once you have reached this point, start ignoring the dog when he
targets the drawer spontaneously (what we call throwing behaviours.)
Only c/t him for targeting the drawer after you have given the verbal
Practice this a bit and you will find that he will stop offering
the behaviour spontaneously. The behaviour is now on cue.
