Spike is the name of the most frequently appearing of Snoopy's brothers in the comic strip Peanuts by Charles Schulz.
Spike's appearance is similar to that of Snoopy, but he is substantially thinner, and sports a long, droopy mustache. Spike lives alone in the desert near Needles, California, only occasionally interacting with the principal characters in the strip, generally in visiting Snoopy. His friends are mostly inanimate cacti. Like Snoopy, Spike was raised on the Daisy Hill Puppy Farm. Among his other siblings are the rarely seen Andy, Belle, Marbles, Molly, Olaf, and Rover.
