The BarxBuddy Dog Trainer seems to solve all these issues. It’s affordable, it’s battery operated and can be carried along while going out and is there all the time, and it only involves the owner and no other person with the dog. The BarxBuddy Dog Trainer is a little larger than a TV remote control with roughly the same dimensions. There’s a slider switch on one side which controls the two modes and switches on the LED lights in the front. Also in the front, there are a couple of ultrasonic sound emitters. Ultrasonic Sound Emitters is the most notable feature of the BarxBuddy as they are large and are up front. They are also the most important feature as the ultrasonic sound emitted by them can only be audible to the dog and, depending on the mode, help train it.
