Query: The Best Book on Canine Behavioral Ecology Yet...

Having at one time fancied myslef an Evolutionary Biologist (until I had to make an actual, lucrative living) I thoroughly enjoyed this dispassionate treatise on canine behavior. I am a lifelong dog owner love them to pieces. This book does a great job of deconstructing the myths of dog behavior and rightly provides criticism of the eugenics of modern dog breeders. A little bit more in this regard would have been desirable to me, but I'm still thrilled that someone is bringing up many of these issues.This book will piss a lot of people off.
