Charles Schulz (1922-2000). The inspiration for Snoopy was the Schulz's insane black and white pup, Spike. The "hunting dog" scoured for pins, tacks and razor blades and was generally uncontrollable. In fact, Spike would often race away from the house anytime a door was cracked open, and it was only his love for going on car rides that brought him back. Any time Spike made an escape, Charles would have to run and start honking his father's car horn repeatedly to lure the dog back home.
