No one told him that he weighs only a little more than a large cat.
He thinks he's BIG...
... and that it's his job to keep track of things around here.
Like all those pesky deer trepassing in the his pasture early this morning.
They weren't frightened by his barking from inside the house...
... maybe he can run them off with the intensity of his gaze.
It hasn't worked yet... but you never know... it could happen. Once they notice him up there in the second floor window, they might be able to tell... just by his stare... that there's at least 100 lbs of fearless protectiveness packed into that little 19 lb package.
