An illegal sport is any sport that is illegal in one or more jurisdictions due to the violent or dangerous nature of the sport. Well-known illegal sports, such as cockfighting and dogfighting, are barred on the basis of animal abuse.
Illegal sports are controversial due to the dangerous aspects attributed to them and the pain they can inflict on humans or animals. They also are controversial due to the perceived nature of some of them-notably dogfighting-as being savage sports.
Cockfighting is a gambling and spectator sport where roosters fight, frequently to the death, in rings, while players place bets on which rooster will win. Often, sharp implements are attached to the legs of the birds, inflicting massive injuries and pain. The birds used for cockfighting sometimes are given stimulant drugs to enhance their fighting ability and make them more aggressive.
According to the Humane Society of the United States, cockfighting is illegal (at least a misdemeanor) in all fifty US states. It is classified as a felony in 39 states. Notable states that have less severe laws are Alabama, Hawaii, Idaho, and Mississippi (misdemeanor punishment for cockfighting; no punishment for possessing cock or being a spectator); South Carolina, South Dakota, Utah, and Kentucky (misdemeanor punishment for cockfighting, no punishment for possessing cocks, misdemeanor punishment for being a spectator).
Governor Frank Keating of Oklahoma said when outlawing cockfighting in his state that "Cockfighting is cruel, it promotes illegal gambling and it is simply embarrassing to Oklahoma to be seen as one of only a tiny handful of locations outside of the third world where this activity is legal." Since there is no reliable data on the status of cockfighting in the third world, it is assumed that cockfighting is largely legal, unpopular, or laws against it are unenforced amongst these nations.
Dog fighting is a practice, illegal in many jurisdictions, where two dogs, often a molosser breed, are put into an area to fight and sometimes kill each other. Dog fighting has been reported as far back as AD 43 when the Romans invaded Britain. Both sides employed fighting dogs, and out of their wartime use grew a sport, which achieved great popularity, particular in Britain and later the United States.
Dogfighting can involve high stakes, and carries with it the same sociological dangers of other gambling, and particularly illegal gambling, activities.
