That's ruff

A doctor is trying to find the source of several bruises on the torso of a boy. Turns out that he was hit with a baseball bat as part of a pledge initiation. Another kid is accused of killing a dog. The dog jumped over a ravine to catch a Frisbee and falls into the ditch on some rocks and bleeds to death. But the kid didn’t even throw the Frisbee, he was just playing with the dog beforehand.
