Snoopy is a fictional character in the long-running comic strip Peanuts, by Charles M. Schulz. He is Charlie Brown's pet beagle. Snoopy began his life in the strip as a fairly ordinary 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 based on Schulz's childhood dogs, Snooky and Spike.
