From the Dog Encyclopedias series, this slender but useful volume introduces terriers in general before offering full-page discussions of 22 breeds and briefly introducing 8 more. Each single-page presentation provides comments under topics such as appearance, personality, breed, background, country of origin, and date recognized by the American Kennel Club. Illustrated with two clear color photos of representative dogs and written in short, succinct paragraphs, the text is very readable and informative. Sidebars spotlight a fun fact or a famous dog. While Gagne points out positive qualities in each breed discussed, readers looking for a new pet will find the carefully phrased comments in the personality, training, and care paragraphs very useful in deciding whether to choose a terrier and, if so, which one. A solid choice for libraries.
