160 pages.The 1981 edition (now out of print) of this little classic on puppy rearing was a word-of-mouth best seller. This substantially revised and expanded edition benefits from an additional decade of observation of puppy behavior by its authors and includes effective, up-to-date methods for educating puppies to become good canine citizens. Along with Job Michael Evans's The Evans Guide for Housetraining Your Dog (Howell, 1987), this is required reading for new puppy owners. Whether the copy still in circulation is battered and gnawed or the book slipped by the first time around, every public library should acquire this new edition, and academic libraries should seriously consider it for its insights into canine behavior. Highly recommended.
