Dog whistle, whistle to silence the neighbor's barking dog, silent and adjustable ultrasonic dog training whistle (black)

Dog whistle to silence the neighbor's barking dog. Silent and adjustable ultrasonic whistle. If no sound is produced, it doesn't mean the whistle isn't working, but that the frequency is incorrectly set. To use it correctly: unscrew the stem, tighten the nut slightly, and blow into it. Adjust the frequency to the one that best suits your pet. This will allow you to train and call your dog effectively. Easily teach them commands like "sit," "paw," "stop barking," etc. Whistle with wrist strap included.
