I came home to find my power out and workers from the electric company working on the lines. I went around to the backyard to see what they were doing since that's where the main power line is. I heard Zero barking at them like crazy. As I looked out the back door, he was running up and down the fence barking at the workers while carrying a rope bone in his mouth. The stupid dog was trying to get these complete strangers to play fetch with him. What an awful guard dog!! Clearly I have failed in my training.
