A great training aid for those who are ″practicing″ under ring conditions. Part 1 is titled ″Invisible Judge″ and has audible judges commands for each exercise, in the order you would hear them in the ring, for all three obedience classes. Part 2 consists of dog show noise, which allows you to condition your dog so they can be desensitized to the many distracting noises commonly found at most dog shows. A great aid for any serious trainer! 60 minutes.
