D.                                            Dr. Dolittle’s Corner    Have you ever noticed your dog carefully when you walk it on the street? When your dog smells the ground,walks in circles, keeps looking at you in the eye suddenly, it’s time for poop.    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 cousins, wolves, we can find one possible answer. In the wild, wolvesusually smell around to decide a good place to poop. Then they walk in circles to make sure there are no otheranimals around. After that, they start to do their business. During this time, wolves must be very careful becausethey 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.
