Hi glitterbag - Cleo isn't really impacted by any kind of physical discipline. Like your grand-dog she thinks it's part of a truly fantastic game. Ignoring her is the only real punishment which means anything to her.
Threat of water stops Bailey in his tracks.
Other dogs are chastened by the sound of the rolled up newspaper thwacked on a piece of furniture.
You'll need to figure out what the little grand-dog wants to avoid.
