🎊Ultrasonic Anti Barking Device is the most humane and effective way to stop unwanted barking, more user-friendly and safer than the electric dog collar. It emits ultrasound that only dogs can hear to stop the dog from barking.
Provide a quiet environment for you and your family when you talk, sleep, work and coax the baby etc.

✒Work Instruction：
Power on: Set the slider to Audio, Ultrasonic I or Ultrasonic II.
Working status: Dog barking will cause the red light to flash and emit ultrasonic waves.
Charging: Red light flashes. The blue light turns on when charging is complete.

🔔Kindly Remind：
1. The maximum detection range is 33 Ft. Beyond this range, the bark stopper will not trigger work due to dog barking.
2. The anti barking device is not suitable for the following situations: aggressive dogs, noisy environments, hearing-impaired dogs, two or more dogs together, dogs under 6 months or over 8 years old.
3. Make sure the bark controller is within range facing the dog and clear of any obstructions.
4. It is not recommended to use the same ultrasound frequency on the same dog for 10 days or more. Dogs may be resistant to the same frequencies. Please change the frequency every 7-10 days.
