Ultrasonic Dog Barking Stopper, Automatic Waterproof Ultrasonic Dog Barking Device for Small and Large Dogs

【Up to 50-Foot Range Anti-Barking Device】 The sonic penetration range is 50 feet, covering both indoor and outdoor areas. Compared to traditional dog training devices, it completely frees your hands. You can easily train your dog's behavior by turning the knob. After testing, the best effect is within 50 feet. The smaller the range, the better the effect.【Effective on Most Dogs】 The device works on most breeds and sizes, but not on deaf or hard-of-hearing dogs. Some dogs may be afraid of or dislike the ultrasonic sound and may not stop barking at first. Please allow up to 2 weeks for training.【Safe Barking Stopper】 Sonic technology is harmless to pets. If the dog is hard of hearing or aggressive, the device may not work as intended. Using one device against two or more dogs barking simultaneously is not recommended.

Ensure the bark controller faces the dog with a clear line of sight. [Rechargeable and Long-Lasting] The built-in 1500mAh lithium battery can operate continuously for 30 days after a 5-hour full charge. The low battery indicator ensures timely charging. The robust IPX4 waterproof ABS housing gives the device a longer lifespan and allows it to be placed or hung anywhere indoors or outdoors.
