Title: The Genius of Dogs: How Dogs Are Smarter Than You Think
Author(s): Brian Hare and Vanessa Woods
Genre: animals, non-fiction, science

Is your dog smarter than a 5th grader? Could your dog possibly be smarter than you? If you answered yes to these two questions, you are not alone. Brian Hare is an animal behaviorist who has been studying canines and their cognitive abilities. Using various experiments, Hare hypothesizes that dogs' genius came about due to domestication. (No, he is not saying that wolves and foxes are dumb but dogs perform better on animal intelligence tests which are talked about extensively in the book)
Hare also hypothesizes that canine domestication occurred through the use of breeding for non-aggressive personalities (friendliness) versus breeding for a certain physical trait.
