Nala surveys our backyard to ensure it is free from squirrels, wild turkeys, skunks, geese, deer, woodchucks, foxes, other dogs and cats. Her level of barking and whining at the door is a function of the proximity of these would be intruders to the house. The approach of a masked man carrying a crowbar, however, would more likely lead to enthusiastic tail wagging. It is amazing to me how much love and adoration this otherwise talent-less creature enjoys. I receive no such attention when I lie around the house all day and pee in the backyard.
