Dogfighting comes from a popular method of air-battle during the first World War. As opposed to firing guns at an enemy aircraft, an enraged Dog, usually a pitbull or similar sized dog was thrown into the enemies cockpit.
Experiments with different breeds led to the popular choice of pitbull, known for its tenacity. Dobermans were effective, although few planes could carry more than one, and chihuahuas, while compact, were nothing more than a temporary annoyance to the enemy.
