If there's one thing you can count on your dog for, it's that you can always count on your dog. Everyone knows that dogs are among the most loyal creatures on the planet. Loyalty also comes from wolves. Despite the common term "alpha male" implying that a male wolf rules over his pack, the fact is that wolves oftentimes mate for life, and mating pairs share responsibility in running their packs of offspring. Living as part of a nuclear family unit is built into your dog's instincts, which is what makes them so loyal and such terrific family pets.
