In my opinion, ADVANCED obedience would include those remaining exercises that you'd use in high level competition, as well as specialized commands used for dogs that do real work, such as guide dog work, hunting and police / protection. (samthedogtrainer.com)
Obedience training ranges from very basic training, such as teaching the dog to reliably respond to basic commands such as «sit,» «down,» «come,» and «stay,» to high level competition within clubs such as the American Kennel Club, United Kennel Club and the Canadian Kennel Club, where additional commands, accuracy and performance are scored and judged.
