As professional all-breed handlers, Bob and Pat Hastings assisted with many of their clients’ breeding programs and bred 28 different breeds on their own. During this time, they researched and developed their structural evaluation process, detailed in the best-selling Puppy Puzzle video. This process is so sensible that it has people “puzzling” around the country and elsewhere! 

The Puppy Puzzle DVD offers both a digital remastering of the original video feature, PLUS a bonus feature that includes 50 minutes of new information about eye color, lines of balance, puppy teeth, front and rear angles, herring gut and long loin, rear assembly weaknesses, and hocks, as well as an introduction to Structure in Action.
