Book excerpt: With the beloved dogs from P. D. Eastman's classic, Go, Dog. Go!, toddlers can explore the world of color in this interactive adaptation of the original book. Flaps, wheels, and slide tabs let children make a white dog get black spots, the traffic light change from red to green, and dogs of all colors zoom around in cars. Simple and sturdy interactive elements will make this new format a hit with parents and little ones alike!
