This compact book is indeed encyclopedic in its coverage of the common and not-so-common pitfalls of canine health. Beginning with an overview of how to have a healthy dog, it then segues into specifics of first aid and emergency care and the more complicated issues of system-based ailments. Neurological, circulatory, respiratory and more are covered. It is also fully illustrated; the diagrams showing how the various systems work are particularly informative. While no book can substitute for a vet’s attention, this one goes a long way toward helping us know when it’s time to seek that attention.
