Veterinarian, animal behaviorist, and dog trainer, Dr. Ian Dunbar received his veterinary degree and a Special Honors degree in Physiology & Biochemistry from the Royal Veterinary College (London University) plus a doctorate in animal behavior from the Psychology Department at UC Berkeley, where he researched the development of social hierarchies and aggression in domestic dogs.

He has authored numerous books and DVDs about puppy/dog behavior and training, including AFTER You Get Your Puppy, How To Teach A New Dog Old Tricks and the SIRIUS® Puppy Training video.

In 1982, Dr. Dunbar designed and taught the world's very first off-leash puppy socialization and training classes -- SIRIUS® Puppy Training. Subsequently, he created and developed the San Francisco SPCA's Animal Behavior Department, the American Kennel Club's Gazette "Behavior" column, which he wrote for seven years, and the K9 GAMES®, which were first held in San Francisco in 1993 and continue as annual events in Japan and France. He hosted the popular UK television series Dogs With Dunbar for five seasons and has appeared on numerous radio and television programs, including the Today Show (US) and Dash Village (Japan).
