a dog looking at the camera

I am half wolverine, half barb wire and all attitude. I am either your best friend or your worst enemy, depending on YOUR attitude. I can herd the wildest cows or the gentlest sheep with equal determination. I can work all day in snow storms, pouring rain or blistering heat and then ask you to throw the ball when we get done. I will argue with you at every turn. After all, I know what I'm doing and the best way to getter done. I am easy to feed. I will eat your steak or the dead, rotten gopher I found in the field. You will never be without a navigator in the truck. (...)
