Great photographs of adorable pups and adult dogs emphasize the author's answers. Ages 8-11.

How Smart is Your Dog?: 30 Fun Science Activities with Your Pet, by D. Caroline Coile; Sterling; (May 28, 2003)
Your dog will act "smarter" if you know more about how he "thinks." Enter the world of canine senses--how your dog sees, hears, smells, tastes, and touches differently from you, and how a dog's life and aging process differ from yours. You even learn to read your dog's mind-brain function, intelligence, memory, and learning abilities--based on its biological origins. The most fun part is the experiments to test your dog's health, reflexes, vision, and scent; or even trace its behavior back to the wolves that are its ancestors. Grades K-5
