Snoopy is a cartoon dog in the long-running comic strip Peanuts, by Charles M. Schulz. He is Charlie Brown's pet dog. Snoopy began his life in the strip as a fairly conventional dog, but eventually evolved into perhaps the strip's most dynamic character—and among the most recognizable comic characters in the world. The original drawings of Snoopy were "greatly patterned" after Spike, one of Schulz's childhood dogs.
