Arthur's new puppy causes problems when it tears the living room apart, wets on everything, and refuses to wear a leash.
Arthur is thrilled when he gets a new puppy. He's had a lot of experience with pets so he knows they're as much work as they are fun.
Even so, when Pal tears the living room apart, wets on everything, and refuses to wear his leash, Arthur gets worried. His parents are unhappy with Pal's behavior and even D.W. seems ready to banish the boisterous puppy to the garage. What if Arthur can't control Pal-and Pal gets sent away to live on a farm?
