The story of the lost dog can possibly take you to a tree house with criminals, a radio station, a police station, a pound or an old man's cabin depending on your choice of story. This story starts with a simple plot and is for 2nd to 3rd grade reading levels. The young boy and his sister go on a few adventures to find their lost dog. In one story, the dog is visiting an old man who is a mad scientist. Another ending included Homer the dog sticking with a hurt puppy, yet another ending finds Homer at the Pound. I would use the story as a motivator to write mysteries .
