The Spanish Fighting Bull is an Iberian heterogeneous cattle population. It is exclusively bred free-range on extensive estates in Spain, Portugal, France and Latin American countries where bull fighting is organized. Fighting bulls are selected primarily for a certain combination of aggression, energy, strength and stamina. In order to preserve their natural traits, during breeding the bulls rarely encounter humans, and if so, never encounter them on foot.

Bullfighting is a physical contest that involves a bullfighter attempting to subdue, immobilize, or kill a bull, usually according to a set of rules, guidelines, or cultural expectations.
