Anyone who wants to understand dog body language or to help dogs play successfully with other dogs will love this book. It is aimed at people interested in running doggy daycare play groups but is a wonderful guide to any off leash dog play.

You can learn as much in the chapter on dog language as you would from a whole book. I especially liked the way each part of the dog’s body was looked at separately and the different signs were described simply and clearly. These descriptions were supported by many very informative photos.

The authors have devised a brilliant Green light, Yellow light, Red light set of management signals. Each expression, sound, etc is aligned with the emotion associated with it and its meaning. Green light behaviour indicates happy play; yellow light behaviours are caution signals and, when the people respond to them by intervening early, Red light behaviours may be avoided.

Play styles are described then divided into the groups or breeds with their usual play styles, their compatibility with other breeds and play styles and management tips to help the play stay fun. The authors note that some breeds come into the Red light category but that individual dogs within those breeds may be able to enjoy play if they’re managed well.

Stress signs, such as lip licking, are also clearly and simply described and once again accompanied by excellent photos. ‘If you begin to see a dog with many stress signals it is time to intervene.’

And if you’re not quick enough there’s a chapter on aggression. Wounds are described by type and severity to help evaluate the incident. Encounters are described under headings like Snark, Tiff, Scuffle and Fight (you have to read it). Aggressive Displays That Precede a Fight include Stiffness, Freezing and Direct Stare and, if you miss those, the authors give advice about breaking up a fight.

The final chapters are Leadership and Controlling the Group and are more directed at play group leaders but still have plenty to offer the single dog owner. The Appendices are great, too.

Anyone who’s serious about learning about dog behaviour needs this book, it has sharpened my observation skills and provided me with an effective framework for assessing behaviour. (Posted on 28/07/09)
