The striking golden palomino pictured on the cover will have this title galloping off the shelf. Do horses walk on their toes? Can you tell a horse's age by his teeth? The author/illustrator team that collaborated on The True-Or-False Book of Cats (not reviewed) takes a similar look at horses in this title. Their affection and admiration for the subject are apparent. Each page includes pictures of horses past and present as well as brief questions and answers. The text is engaging, introducing historical facts and anecdotes: the discovery of the wild horses of Mongolia by Russian explorer Nikolai Przewalski in the 1800s and the career of Clever Hans the counting horse who toured Germany in the early 1900s. Other pages describe the specialized anatomy of the horse: leg bones, teeth, eyes, hoofs, sense of smell, and something about horse behavior. The illustrator extends the text with thumbnail drawings of horse incisors at different ages (yes, you can tell the age of a horse by his teeth) and humorous sketches of horses with balloon captions explaining the message of nickers, snorts, whinnies, and squeals. An appealing title for animal lovers and horse enthusiasts. (Nonfiction. 8-10)
