It is a stormy evening when Doggie Daddy hears a knock at the door and finds that it's a little duck. Doggie Daddy is allergic to ducks and quickly shuts the door. They hear a knock at the door again and Augie answers it so his dad won't have to be close to the duck and he finds that the slamming door bent the little duck's bill. He takes him in and his dad quickly kicks the little duck out again.
Later, Doggie Daddy is taking a nap and the little duck taps on the window and Augie lets him in and feeds him. His dad wakes up and finds the duck and starts to chase him out of the house. Augie creates a formula that should help his dad's allergies and gives it to him. His dad is no longer allergic to ducks and now he wants to eat the little duck. Augie quickly works on another formula.
By the time Augie catches up with his dad with the new formula, his dad has caught and eaten the little duck. The duck escapes and Augie gives his dad the formula. Now his dad acts like a duck and starts to fly and head south for the winter. Augie drinks the formula and joins his dad and the duck and they all head south.
