Tramp supposedly takes a nip out of pampered young Alan Edgerton and the court case that follows, gives Robbie the chance to help out the family's lawyer with some special investigating when he realises he can prove that the dog acted in self defense.

Chip is thrown out of the neighbourhood clubhouse because he cannot convince the older boys that he is all grown up. He makes a bargain -- he will fight one of the older boys for the privelege of becoming club mascot. But he doesn't count on being sent to hospital to have his tonsils removed the very day of the big fight.

Chip comes to the rescue of a trapped dog and receives a reward, which leads to new found popularity with his fellow members of the club that he and Ernie wish to join.
