(20-23)
         You are walking your dog on the street, and suddenly, your dog smells the ground, walks in circles, keepslooking at you in the eye. Yes, it’s poop time!
         Do you notice every time before your dog poops, it does the same things—smelling, walking in circles, andlooking at you? Why? By looking at dogs’ close cousin, wolves, we can find one possible answer. In the wild,wolves usually smell around to decide a good place to poop. Then they walk in circles to make sure there are noother animals around. After that, they start to do their business. During this time, wolves must be very carefulbecause they can be easily attacked, so they keep their eyes on each other by watching each other’s back.
         Now you know why your dog does certain things every time it poops. This also explains why your dogfollows you to the bathroom. It’s just trying to pay you back!
