A dog leg gearbox is a manual gearbox with an unusual shift pattern:

Dog leg pattern gearboxes are usually found on performance and racing automobiles. This is because in road racing it is rare to shift into first gear other than for the initial start or exiting a pit lane.
Notable street cars to feature the dog leg pattern are the Porsche 914 and early 911 and Lamborghini Miura.
