Dog fighting is a type of blood sport that turns game and fighting dogs against each other in a physical fight, generally to the death, for the purposes of gambling or entertainment to the spectators. In rural areas, fights are often staged in barns or outdoor pits; in urban areas, fights are often staged in garages, basements, warehouses, alleyways, abandoned buildings, neighborhood playgrounds, or in the streets. Dog fights usually last until one dog is declared a winner, which occurs when one dog fails to scratch, dies, or jumps out of the pit. Sometimes dog fights end without declaring a winner; for instance, the dog's owner may call the fight.
Dog fighting generates revenue from stud fees, admission fees and gambling. Most countries have banned dog fighting, but it is still legal in some countries like Japan, parts of Russia, and Albania.
Dog fighting is still held in a few places in Japan, the most famous being Kochi and Akita prefectures, but gambling on dogfights is now illegal.
