The Chipmunks have just got back home from a long performance tour. While Dave, Simon, and Theodore are cleaning up the house, Alvin tends to his garden only to get into a match with the neighbor's dog who keeps burying its bone in his garden. Even after talking to the neighbor, the dog keeps harassing Alvin and his garden. Tried of dealing with the dog, Alvin rushes to get a whistle after Simon reads him part of Dog's Life. It's not long before he realizes the whistle's side effect.
