Anti Barking Device for Dogs,50FT

Efficient&Safe: This dog trainer does not cause any harm to dogs. An anti barking device with two safe ultrasonic frequencies, a stable frequency of 25kHz and a fluctuating frequency of 25kHz to 30kHz, can provide humane and safe dog training while avoiding immunity to a single frequency. Four times faster than stopping barking with a dog whistle, using a training dog horn, barking box, barking collar, using an air horn, or personally training a dog plan. A pet corrector suitable for dogs aged 6 months to 8 years old. (This product is not effective for dogs with poor hearing)
The 50 foot wide ultrasonic coverage allows for flexible immediate use indoors and outdoors, protecting you and your pet from harm from other dogs in the distance. You just need to point and press the high/low button, and the dog will immediately react and stop bad behavior. Please note that if your dog loses hearing, our device will be ineffective.
