Wolves run in packs, and comumicate through their howls. Each set of howls, may have a different meaning. The wolf will howl in responce to a pack call, another wolf, or even the sound of a whistle. The pack howls to protect their teritory as well. I love the sound of a good howl.
Wolves take on a lifelong mate, and like human families live together, and protect each other.
Too bad humans weren't more like the wolf. Wolves,,,, The wonderful, mysterious, and beautiful animals, that we need to love, respect, and care for.
