Watch Dog

No squirrel, no chipmunk, no crow, starling, or blue jay can escape the vigilant gaze of my fearless hound.  Not one single delivery person, mail man, or passer-by can elude the instantaneous volley of sharp barks that erupt from the throat of this mighty creature the moment she detects any unauthorized activity in her domain.  There will be no shenanigans around here while she's on duty!
