The device emits a high-frequency ultrasonic sound that is inaudible to humans but irritating to dogs. This sound interrupts barking or unwanted behavior and helps train dogs to stop barking or biting.
The device has a range of up to 20 to 30 feet, making it suitable for both indoor and outdoor use. The effective range may vary depending on the environment and any obstructions.
The color screen displays important information such as battery level, mode settings, and the intensity of the ultrasonic frequency. It also provides visual feedback, so you can monitor the device's activity and effectiveness.
The repeller is most effective for excessive barking, especially in situations where dogs bark due to boredom, attention-seeking, or anxiety. It may be less effective for barking triggered by fear, pain, or aggression.
