My trainee is trained! He's in undies and dry both day and night. We've even weaned him off the treats. There may be set backs still, but for some reason I just don't think so.
Now my trainee is training me. He has a buzzer and bell system and I'm not sure where he learned it, but it works like this...
Z: May I have a cookie?
Z: Bzzzzt. (wrong answer)
May I have a cookie?
Z: Ding. (correct answer)
How long, do you think, before this gets old?
