Jerry Springer, looking to pare some pork, took a jog along Chicago’s lakefront — but ran so far he was pooped. Taking a shortcut home, he jumped the fence of a recycling center — then heard the patter of little paws and “GRRrrrrr! . . . BOW WOW!” A howling, growling guard dog was racing right toward the seat of his pants! Jerry shinned up a tree, hopped onto a shed roof — then waited glumly until the place opened up an hour later — and Fido was leashed!
