High Quality Content by WIKIPEDIA articles! Snoopy is an 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 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 "slightly patterned" after Spike, one of Schulz`s childhood dogs.
