?Are you worried about your neighbor's dog barking??Sorry, but this product doesn't magically stop your neighbor's dog from barking. However, if your dog barks randomly and disturbs guests or neighbors, maybe you can be patient and use this product to train and guide your dog. ?Roughly interfering with dogs doesn't deserve recognition?If you want the dog to stop barking, rough barring or using an ultrasonic whistle is not a good way. The dog will just be confused and possibly more moody. ?Reward and guidance is a good way to train dogs?After the dog shows the right behavior through our guidance, we should reward the dog appropriately so that the dog can confirm that this is the owner's instruction or the owner's behavior supports. We introduce the training part method for reference. ?No ultrasonic and can be heard by human ears?The function of the dog whistle is to help training. Only through training can the dog understand your instructions and act accordingly. And there may not be a magic dog whistle in the world that can manipulate a dog to do anything. ?Let's play with the dog?The dog whistle is a good tool for interacting with the dog. You have to be patient, and when the dog finally understands your commands and makes the moves, your joy will be unprecedented.
