Dog Packs [PDF ebook] 

While most of dogs we’re familiar with live among humans, wild dogs live very different lives, revolving around the pack. Like an army, dog packs depend heavily on rank to function. Easy-to follow text is accompanied by clear photos showing coyotes, dingoes, and other wild dogs in their natural habitats and illustrating for readers what living in the wild is like for dogs. Dog owners may even come away with a better understanding of their own pet’s "pack mentality."
