Adjustable 9 Gears: Our ultrasonic dog barking device features 9 adjustable gears to accommodate dogs of different ages and breeds. The sound frequency is precisely calibrated and distributed across these gears, making an allowance for effective training by step by step adjusting the gears.
Silence Dog Whistle: Utilizing the variance in frequency perception between humans and dogs, our dog barking deterrent emits harmless ultrasonic waves ranging from 25kHz to 40kHz. Even as inaudible to humans, these waves act as a clear whistle to capture dogs’ attention.

For added convenience, we provide a matching neck strap, ensuring effortless handling. Moreover, our product features an integrated LED flashlight, making midnight dog walks more convenient.
USB Rechargeable: Bid farewell to battery concerns with our rechargeable ultrasonic dog training device. A simple 2-3 hours charge provides 3 months of standby time and 30 days of usage.
