Knittingham Puppy Farm is a farm in the city of Coolsville owned by Mrs. Knittingham, in which Scooby-Doo's brothers (Howdy-Doo and Skippy-Doo) and his sister Ruby-Doo were born. Scooby's parents, Dada-Doo and Mumsy-Doo also lived at the farm with Mrs. Knittingham (and later moved back to Dooville). It is located on a huge hill.
