Dog

This portable ultrasonic device helps reduce excessive barking by emitting high-frequency sounds that dogs find unpleasant. It works indoors and outdoors with three different modes to suit various situations, plus an LED light for visibility. The compact design makes it easy to carry around, and it's a non-harmful way to discourage unwanted barking without using treats or training commands.
