【Automatic Dog Barking Stopper】This device intelligently captures dog barks from up to 15 meters away and automatically emits an ultrasonic sound that distracts your dog to stop unwanted barking, allowing you to enjoy a moment of peace and quiet.

【Dog Barking Stopper】The ultrasonic frequencies are harmless to pets and completely inaudible to the human ear. If the dog is hard of hearing or aggressive, the device may not work as intended. It is not recommended to use this device against two or more dogs barking at the same time.

【3 Operating Levels】The adjustable frequency dog barking deterrent is suitable for different dogs. 15kHz-30kHz is suitable for large, aggressive dogs. 20kHz is suitable for gentle dogs.

30kHz Suitable for small dogs. Recommended for dogs aged 6 months to 8 years.

【USB Rechargeable】The ultrasonic dog repellent has a built-in rechargeable lithium battery. The device can operate continuously for 30 days after a full 5-hour charge. The red/blue color indicates the battery status.

【Easy and Waterproof Installation】The anti-barking device can be hung on a tree, wall, or fence to prevent your own dog or your neighbor's dog from barking. Ensure the bark controller is facing the dog and is within easy reach without any obstructions.
