Clary growls for all occasions. She growls when she plays and when she sleeps. Those are good growls. When She is on alert and doing her job, or thinks she is doing her job her growls can be a very scary experience. It is not one of those wimpy growls, she is a big dog with a deep serious voice, of course chasing away the unwanted is her job. Most of the time she jumps up and barks which is scary in the ‘boo’ sort of way but not in the ‘Uh Oh…Something Bad’s About to Happen’ Sort of way.
Great Pyranees are not only guard dogs but they are nocturnal. One late night, around two in the morning I heard the growl, chances are she heard a deer outside, a truck going down the street, a leaf blowing in the neighbours yard. Trying not to wake Denyce I try to calm Clary before she goes into an all out barking frenzy.
The growl deepens, “Clary” I stage whisper, “come here!” As I tap the side of the bed. Clary loves to be touched and calms her right down. But as my fingers dangle off the edge of the bed in total darkness feeling for Clary’s big snout I can’t help but wonder if this is a good idea. There is always the possibility of losing a finger or two. But dismissing the thought as her growl comes again, I repeatedly call her over while trying not to wake my wife. But alas I hear my wife mutter in a groggy voice, “you ever wonder if it’s us she is thinking about attacking?
