ZLOLEN Rechargeable 50ft Ultrasonic Dog Bark Control Device with 2 Sonic Emitters

Efficient and accurate: it can accurately detect dog barking. When the sound of the dog's barking exceeds 84 decibels, which affects people's normal life, it will automatically emit ultrasonic waves to attract the dog's attention to stop the dog barking. Powerful and strong: To pursue a better effect, our barking control device is designed with 2 sonic emitters. Compared with a single-head transmitter, our device has a wider range of emissions and can emit ultrasonic waves at different angles and directions at the same time. Thereby the coverage area and penetration are improved. Safe and harmless: Compared with the shock collar training device, the ultrasonic bark box does not cause any injury to the dog, which is a safe and humane way to stop the dog's bad behaviors. Ensuring the safety and health of dogs and humans.
