Disc dog (commonly called Frisbee dog) is a dog sport. In disc dog competitions, dogs and their human flying disc throwers compete in events such as distance catching and somewhat choreographed freestyle catching. The sport celebrates the bond between handler and dog, by allowing them to work together. The term 'disc' is preferred because 'Frisbee' is a trademark (held by Wham-O) for a brand of flying disc.
