Equipped with two ultrasonic emitters, it delivers customizable, high-frequency sound tailored to individual dogs, ensuring effective barking control for various breeds. 🐕Multiple Function Modes: This anti barking device offers four different modes for optimal control. In ultrasonic mode, it emits a powerful SOS flash and ultrasonic sound to stop barking. The sound warning mode uses a dog whistle-like 'beep' to discourage barking. The fixed frequency mode delivers steady 25 kHz ultrasonic waves, while the fourth mode alternates ultrasonic frequencies to prevent your dog from becoming accustomed to the deterrent. 🐕 Wide Coverage Range: This dog training device is suitable for both indoor and outdoor use, with an effective range of up to 16.4 feet. It is intended for dogs aged 6 months to 8 years, but is not recommended for dogs with hearing impairments or hearing loss. 🐕Correct Your Dog's Behavior: With multiple modes to choose from, you can select the most effective option for your dog's needs. This bark control device works similarly to a dog whistle, helping modify your dog's behavior. When using the device, you can pair it with a command like ‘stop.’ With consistent use, your dog will learn to associate the command with stopping the barking, developing a conditioned response over time. 🐕Helpful Tips: The anti-barking device offers excellent battery life, lasting up to 30 days on a full charge. It comes with a 5V USB cable for easy charging via a computer, adapter, or other sources. Plus, it uses ultrasonic technology that is completely safe for both humans and dogs.
