Dog Training and Eight Faces of Aggressive Behavior: A Master's Solution to Barkers, Growlers and Biters
Matthew Duffy began training dogs professionally in 1980. He is the owner and operator of Duffy's Dog Training Center, where he oversees the instruction of several hundred dogs a year.            In 2009, Matthew published his very popular "Ten Natural Steps to Training the Family Dog" (Building a Positive Relationship). As a compliment to this obedience guide, Matthew professionally produced a two DVD set that covers "Canine Manners" and "Formal Commands".       During his formal study of behavior at Indiana University, Matthew was inducted into the National Honor Society in Psychology. Through his study and more than thirty years of experience training dogs for every imaginable purpose (family obedience, handicap assistance, search and rescue, scent detection, police work, AKC competition and Schutzhund sport); Matthew has developed into a true master of his trade.       Matthews latest endeavor was the founding of WhiteFangVentures.com, an online dog training source. He lives in Indiana.
