The Canine Activities - Obedience Trials FAQ is a thorough resource for people interested in entering their dogs in dog shows which feature obedience as an event. Included are a history of the American Kennel Club's Obedience Trials; a list of organizations which offer Obedience Trials; overviews of the AKC and other groups' exercises and requirements for titles; opportunities for mixed breed dogs; help with show stress, hints for handlers and hints on dogs' attire. An acronym list, glossary, and resources are also provided. Currently the FAQ's main focus is North America; they are interested in obtaining more material on international trials.
