Turns out that foxes are pretty social animals - although they always hunt alone -, and some live in packs that usually include one dominant male and up to five females. The young males emigrate. Instead of breeding, young female foxes can help to feed the weaned pups and to protect them against predators such as wolves. The exact effects of that kind of help in raising youngsters is not clear yet. However, in some areas only one couple lives and they protect that territory against other foxes and predators. But in both cases, once the puppies are old enough to hunt for themselves, the family splits and everyone goes their own way. Independent little thingies!
