After Timmy’s embarrassing walk, and a few other activities, the game of house ends and everyone switches back except for Timmy, and to his surprise, a female version of himself has taken his place at the party.
Later Timmy’s mother arrives to pick up her daughter and her “Dog”, Timmy. They ride home and Timmy truly begins getting use to his new life as a pet.
First he learned how to eat from a bowl, not at the table, then he learned proper pet games, and he began learning commands.
Timmy wasn’t taking it so well, as he kept trying to act human and disobey his “Owner”, eventually leading to him needing obedience training from a professional.
After weeks of shock collar and slightly too rough training, Timmy completely forgot his old life and became a completely obedient pet, and he loved his new life.
