Hi, my name is Mischief and I’m the Chief Security Officer for my owner’s property. I ward off unwanted visitors and passing critters and if I have to hang on the wall to tell them to Bark Off…er…Back Off, I can and do, sometimes up to 30 seconds. My upper arm muscles are big! (I’m really very sweet when I’m Off Duty.) NOTE: Sorry about the quality, it was taken from a camera, not vid camera.
