Dennis Hayre has been training retrievers in field trials, hunt tests and hunting since 1991.
He has put many Master Hunting titles on dogs and qualified dogs for and in Master National events. Maybe even more important to you, he has taught many others to train their dogs to compete with and hunt at the highest levels.
His training methods not only work for hunting dogs, they also apply to the family pet.

This book is not about training methods, but rather about the importance of having the proper mindset before beginning to apply any given method. This is why the principles are applicable to all forms of dog training and dog sports. This book is written in the form of a fable to make the principles more interesting and accessible.
