Klein Brands' ShakeTrainer is designed to permanently stop barking, chasing, chewing, digging, door charging, going potty indoors, jumping up, mounting, play biting, leash pulling, raiding garbage, running away and stealing food. “I followed the instructions on the DVD to introduce my dog to the ShakeTrainer. To my surprise, he responded exactly as the DVD described within a few minutes. He really does not like the sound this tool makes when you shake it and quickly realized that he would not get a treat when he heard this sound. The ShakeTrainer is very effective at getting him to stop what he's doing,” one tester said.
