Let's play with the dog: the dog whistle is a great tool for interacting with the dog. You need to be patient, and when the dog finally understands your commands and takes the reins, your joy will be unparalleled. 【No ultrasound and audible to human ears】 The function of the dog whistle is to support training. Only through training can the dog understand your instructions and act accordingly. And there may be no magic dog whistle in the world that can manipulate a dog to do anything. Reward and a manual are a good way to train dogs: after the dog has shown the correct behavior through our manual, we must reward the dog appropriately so that the dog can confirm that this is the owner's instruction or that the owner supports the behavior. We present the training method as a reference. 【Harsh treatment of dogs is not worth recognizing】 If the dog needs to stop barking, harsh treatment or the use of an ultrasonic whistle is not a good method. The dog will only become confused and possibly more angry. Are you worried about your neighbor's dog barking? Unfortunately, this product will not magically make your neighbor's dog stop barking. But if your dog barks randomly and disturbs guests or neighbors, you might want to be patient and use this product to train and guide your dog.
