there's only a few commands i yell to get his attention... "NO" and "NO WHINING" the latter of which i yell from the bedroom so he can hear me in the kitchen and will shut up when he hears the command. everything else, i say with a mild volume but changes my tone.
i did the "NO WHINING" command at my friend's place once. bunjee was getting a timeout and was in his crate so he started to whining. i yelled "NO WHINING" from the kitchen (he was in the living room) and he quieted down immediately. my friend thought it was a "neat trick" and wondered if it'll work on kids as well as pets.
