Explains how dogs and wolves descended from the ancient wolf, but have evolved into very different animals, then discusses both the similarities and differences between how the two animals behave. He's wagging his tail, fetching the Frisbee, and eager to get petted--in short, Fido's living up to his title as "man's best friend." But the domesticated dog's got a special secret: in many ways, he's really a lot like a wolf. Using amazing close-up images she shot inside a real wolf lair, as well as museum-quality historical pictures and illustrations, award-winning author and photographer Jenni Bidner compares the pet pup with his wild ancestor. Why did dogs become dogs and wolves stay wolves? Should you ever have a wolf in the house--or a hybrid? And exactly why do dogs like to lick your face? Along the way, Bidner debunks popular myths about wolves and provides a true and fascinating look at their behavior.
