When a stranger (as defined above) comes into their presence, they engage in whay we've come to classify as recreational barking. You can probably imagine what this is, but for the uninformed, it means to incessantly bark, over and over and over, at said stranger.

Based on his size, our tri-color Collie named Dougie has a real deep bark that would give pause to the most fearless of burglars or anyone else who might entertain engaging in some nefarious activity against a member of their family. The picture below captured Dougie advising a stranger, by his definition, to stay away from his property:

If you look real closely at his mouth, you can actually see a bark emitting from his elongated mouth. ______________________________________________________________________
