When Red Fox pups are born, they weigh less than a stick of butter and have charcoal gray fur (with the characteristic white-tipped tail). Eventually eyes open, fur grows more dense and teeth begin to come in. For their first month the pups remain in their den, and then, cautiously at first, emerge into the great outdoors.
Around the time they are leaving the safety of their den the pups are engaged in another important process – that of establishing a strict dominance hierarchy. The largest member of the litter, male or female, usually becomes the alpha pup. This position allows it to steal food from its litter mates. Each pup steals food from litter mates below it in the hierarchy. Should food become scarce, the dominant pups get a larger portion of the food and have the best chance of surviving while smaller and more submissive pups may die. By the time the pups are spending enough time outside the den to be noticed by humans, the hierarchy has been established, and we are witness to the less aggressive, playful, puppy-like behavior we associate with fox pups.
