So, I ran across this site while surfing today and it looks like it is very much under construction. There some chapters drafted, though, so if you're interested in K-9 SAR, this looks like it might have potential and perhaps you could contribute. Regardless of how far the draft gets, there's a good list of SAR dog teams at the bottom of the page.
The purpose of this book is to provide practical information to current and prospective SAR dog handlers. Since there are many different approaches to any element of SAR dog training, this book will be most useful if different opinions and approaches are documented simultaneously rather than constantly overwriting each other. If you see an error or have something to add to existing content, do so. If you have an alternative view, add this view rather than deleting existing content.
