Humane Ultrasonic Technology
The 35-45 KHz frequency is unpleasant to dogs but inaudible to humans. When an aggressive dog approaches, point and press—the sound deters them without causing pain or lasting effects. It’s a humane alternative to chemical sprays for everyday encounters.
Double Duty as Training Tool
Beyond deterring strange dogs, this device helps train your own pets. Use the ultrasonic signal to interrupt unwanted behaviors. The same technology that deters aggressive dogs can help correct barking, jumping, or other issues at home.
