Ball Dogs ( Originally BallDogz TM from BioPetz,inc, though most are imitation products ), are a genetically engineered subspecies of canine designed as pets, similar to lap dogs. The main difference from natural dogs is that ball dogs have only vestigial legs, that only serve to keep them from rolling over. This “feature” made it more convenient for owners to manage these pathetic beings, making them suitable only for life as a sheltered pet.

Most brand name ball dogs come with a “base” that maintains their biological functions. Typically the ball dog’s owner will place the ball dog in the base overnight for “charging”, and remove them during the day when they often are carried around, or set in a secure place like a purse when not being held.

The Planetary League placed Ball Dogs on the official list of “cruel organisms” shortly after their introduction in GSC 255. This designation made them illegal to poses or create inside the League.
