Alpha females are second to the Alpha. Their primary job is to reproduce and care for their litter. When not pregnant or caring for a litter, the Alpha female will attend the hunt and stay close to the Alpha. She is permitted to sleep closest to the Alpha. Although second to the Alpha, she is still above other members of the pack. When caring for a litter, she will remain close to the den, alert to potential danger and ready to protect. In the first few weeks of a pup's life, the Alpha female is responsible for teaching him the basic rules of pack life. By the time they leave the den for good, the Alpha female should have prepared them for life outside. She continues to teach them until they are old enough to take on their own role within the pack, including attending the hunt. The role of Alpha female can often occur with dogs that live with just one human. As a two-dog-pack, these ones must stick together for survival. The bond is often much stronger than that in larger families. At home, this can seem harmless, and usually is, so long as the "Alpha female" role is assumed by the dog and not the owner. If this role becomes reversed, this can lead to overly protective behavior from the Alpha dog. After all, in the wild, no dog would mess with the Alpha's girl. A dog does not protect his master, he protects his subordinates. This could be dangerous. Also, an Alpha female will protect her litter, even from fellow pack members. This sometimes presents problems within larger families. If a dog mistakes his place within the family, he may accept one person as the Alpha, but assume the role of the Alpha female. The result? The husband becomes the Alpha, but the wife is out ranked by the dog (or vice versa between husband and wife). The dog then tries to "mother her litter", or the children, becoming aggressive towards anyone that attempts interaction with the children, including the wife.
