As the co-human of a dog that occasionally forgets he is wearing a leash, I think this is a great idea… however, it has better be chew-proof.
Simply attach this training aid between your dog’s leash and collar, and walk him as usual. When he pulls on the leash, a brief, high-pitched whistle reinforces your verbal command to “stop.” Unacceptable behavior usually ceases within 2-3 days. Safe, non-electric, and effective for any size or breed of dog.
