Features:
1.3 ADJUSTABLE LEVELS: The anti-barking device has 3 sensitivity levels (effective range at 15, 30 to 50 ft) and a test level. There are 3 frequency levels (15-30KHz, suitable for large playful dogs; 20kHz for gentle dogs; 30kHz suitable for small dogs).
2. USB rechargeable: the anti-bark device requires no installation of a battery and can be used for up to 30 days on a 5-hour charge. The power indicator can be set to "off" to protect the battery when you are not there.
3. AUTOMATIC: When excessive barking is detected, the dog bark deterrent detects barking and activates the component that effectively prevents the dog's barking and does not require a receiving collar. Sensor distance up to 16 feet.
4. Ultrasonic: dog barking control devices emit a safe, high beep wave that can be heard by dogs, but not by humans. The dog is stimulated by the sound and stops barking. Suitable for all dog breeds and sizes.
5. Portable: the ultrasonic barking guard is designed to look like an alarm clock. It can be hung from a tree, anywhere in the home or in your garden, placed on a table or elsewhere.
