Snaggletooth the lion escapes from the zoo and is on the run from the police. He seeks refuge at Augie Doggie and Doggie Daddy's house. Augie answers the door and the lion begs for Augie to let him stay. Augie tells Snaggletooth to act like a rug so his dad won't realize that he's a real lion.
Poor Snaggletooth has to endure getting banged on the floor, burned by a pipe, and getting whipped to get the dust off. All of this pays off and Doggie Daddy thinks that he is a rug. The police come by and tell them that the rug is Snaggletooth and Doggie Daddy shows them that he's just a rug and the police believe him. Snaggletooth can't take it any more and tells Doggie Daddy that he is a real lion. Doggie Daddy is about to shoot him and Augie tells him that he's his friend and he's harmless. Doggie Daddy lets him stay and Augie studies his homework with Snaggletooth.
