Fraggle Rock Sprocket

Sprocket is an intelligent sheepdog owned by Doc, the inventor of Fraggle Rock, and proves the motto that dog is truly man's best friend. He spends much of his time in Doc's Workshop, where his bed and food dish are, observing Doc at work. Sprocket is very communicative and frequently talks to Doc by barking lively, giving facial expressions, or by pointing to objects in a form of charades. Doc often relies on Sprocket to help with household chores, including repairs on the water pipes.
