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.
