Meloive Rechargeable & IP67 Waterproof Dog Training Collar with 800m Range and 99 Vibration, Shock, and Sound Modes.

Recommended training steps: In case of unwanted behavior: 1. Alert your dog with an audible signal. 2. If your dog doesn't respond, use the vibration mode. 3. The vibration mode can be effective for some dogs and interrupt their unwanted behavior. If your dog still doesn't respond to the vibrations, briefly use the shock mode (the intensity is adjustable and completely harmless to your dog). After these various training signals, your dog will stop its unwanted behavior each time it hears the beep. Typically, neither the vibration nor the shock mode will be necessary again. The receiver is 100% waterproof and works even underwater, so your dog can swim freely with the collar on. 800-meter range: The remote training collar uses the RF434MHz frequency and offers a range of up to 800 meters, allowing you to easily train your dog in the park or yard. Suitable for all dogs. The durable, adjustable TPU collar (sizes 16 to 62) fits small to medium-sized dogs. Rechargeable remote and receiver: Thanks to lithium-ion batteries, both the remote and receiver have a long life (1 to 2 hours of charging provides 7 to 14 days of use). The automatic power-saving mode further conserves battery power when the devices are not in use.
