The common belief that the dog looks at man as a dog has always trouble me. I firmly believe that this remarkable creature knows he is a dog and I am a man. With this being understood, I do not for a second accept that my dog deems me the head of a non-existent pack. I will relay what I believe to be true on this subject. It is for you to find your truth.
First of all, let me state that I do not believe the domestic dog to be a pack animal. I believe he is a social animal. Let me state why. The wolf is a true pack animal, choosing to be with other wolves over man. In fact, he shuns man, avoiding him at all cost. Even in the confines of a zoo, the wolf is noticeably bothered by the presence of man. Which makes it so frightening when these Jekyll & Hydes or wolf hybrids, are offered for sale to the public. The dog leaves his own littermates to follow man. Avoiding, even protecting against other dogs, his two legged companion.
No other animal is so bound to mankind as the dog. It is only man that so foolishly effects this bond by desiring to be a dog or the dog to be man. Instead of accepting the relationship for its uniqueness, man shows his stupidity by inventing unseen forces he calls drives, and tries to control by calling himself alpha, a situation that is already naturally balanced.
