The Frisbee has served as a flying summer favorite for man and his best friend. In 1958, Wham-O, the company that brought us the hula-hoop, first marketed the airborne toy. According to legend, the craze of tossing to canines began in 1974, when a man illegally threw his dog a disc during a break in a Los Angeles Dodgers baseball game. Since that stunt, which landed the owner in handcuffs, canine competitions have leapt up around the world.
