A stock plot about pet ownership in three acts.
In the first act, we meet Alice and her pet dog Tropey. Tropey is a good boy, though he does have a few bad habits and obvious flaws. He tries Alice's patience, and after he misbehaves at a key moment, she loses her temper and sends him away. In the second act, sad Tropey is all alone while Alice is happily playing with Fido, a new pet who seems to have no flaws. But in the third act, Alice falls into danger (sometimes as a direct result of the new pet; other times unrelated). She cries for help, and it is Tropey who comes to her rescue. All is EasilyForgiven and everyone learns the valuable lesson that pets enrich their owner's lives in a way that more than compensates for the times when they're an inconvenience.
Bonus points if Tropey comes to the rescue while Fido runs away or does nothing, or if the habit of Tropey's that annoyed her so much is the very skill that saves her.
Compare with TimmyInAWell, AndroclesLion, and TropeyComeHome.
