Review on 🐢 Rechargeable NLUS Ultrasonic Dog Bark Deterrent - 3 Frequency No Bark Control Devices with 16.5 Ft Range - Effective Dog Whistle to Stop Barking by Warren Hess

Revainrating 4 out of 5

Keep the cat away!

Once upon a time there was a cat that followed my dog every day. The cat stopped on the sidewalk in front of my house and my dog kept barking. My landlord was of course unhappy with the barking and complained. The NLSU bark device scared the cat away and my dog knows he'll stop barking as soon as I grab him. Thanks for saving my madness!

This dog repeller generates ultrasonic in the dog's hearing range from 15Hz to 120KHz, ensures the sound can attract the dog's attention but does not damage the hearing of humans and dogs, can work effectively on dogs older than 6 years old are months or weigh more than 4.5 pounds.
