Considering the technical details and the principle behind the ultrasonic device for barking dogs, this is a quite simple but effective product. With a frequency of 30,000 hertz and more, the sound is actually inaudible to humans. Since dogs can perceive up to 45,000 hertz, it is quite conceivable that your four-legged friend will stop for a moment and draw his attention to it.
With regard to dog training, however, it is important that the dog learns from the beginning that the sound means that he is showing undesirable behaviour. Only in this way can the Barx Buddy be used sustainably and, above all, in the long term.
However, the sound alone will not be able to calm barking dogs. This is where your action is needed. As soon as the device for barking dogs gains the attention of the four-legged friend, it is up to you to correct the undesired behaviour.
The installation of the LED light is also very useful. Not every dog reacts equally well to sounds. Some four-legged friends can handle optical stimuli better and so the device for dog training is also aimed at these animals.
