BarxBuddy (new)

The BarxBuddy ultrasonic training device is lightweight and runs on a 9-volt battery (included). It measures 5 ⅜” x 2 ⅛” x 1” and is about the size of a small TV remote control. When the ON button is pressed, the device emits a 30,000 hertz frequency, which is inaudible to humans but immediately catches your dog’s attention. The BarxBuddy remote ultrasonic dog trainer is safe to use. The high-frequency sound is an annoyance to dogs, so it gets their attention and allows you to correct unwanted behaviors without raising your voice or touching your dog.
