The Dog Training Collar is a lightweight and durable collar that is perfect for training your dog. The collar features three safe modes that allow you to train your dog effectively and humanely. The beep mode creates a loud alarm that will get your dog’s attention, while the vibration mode creates a low-level buzz that will help you train your dog. The shock mode delivers a strong electrical charge that will help you correct your dog’s bad habits. The collar is made from skin-friendly and comfortable nylon and is adjustable and waterproof.
