Simply put, the Alpha is the leader, in every sense of the word. He has full control and responsibility for the pack's survival. He is responsible for providing food, shelter and protection. The Alpha must be quick to settle any potential disputes within the pack and to warn off or if needed, fight off any potential threats. From the pack, he chooses one female. She becomes the Alpha Female, second to the Alpha. Only these two dogs will reproduce within that pack. This is to ensure the reproduction of strong, healthy offspring.
