Imagine walking along with your dog some dark night, and someone approaches suspiciously making you a little nervous. You give a silent hand signal, and, or say, "Warn Him!, and your dog erupts into a cacophony of barking?

In this episode a puppy that is currently starting to nuisance bark is taught instead - to bark only on command - and the command is - "Warn Him". Just a trick, so we're not taking on the risk and associated liability of actually encouraging aggression, but in these uncertain times, perhaps a handy trick, in these uncertain times, a handy one.
