Play with your dogA dog whistle is a good tool for communicating with dogs. You need to be patient, and when the dog finally understands your command and makes a movement, your joy will be infinite. No ultrasonic sound, that can be heard by humansThe role of the dog whistle is to assist in training. Only through training can the dog understand your instructions and take the corresponding actions. There may not be a magic dog whistle in the world that can manipulate dogs into doing something. Reward and guidance are good ways to train dogsWhen the dog shows the correct behavior under our guidance, we should reward the dog appropriately and let the dog confirm that this is the owner's instruction or support. Introduce the method of the training section for reference. Rude intervention with dogs is not worthy of recognitionIf you want your dog to stop barking, rude prohibition or the use of ultrasonic whistles are not good manners. This will only confuse the dog and may make it more moody. Are you worried about your neighbor's dog barking? Unfortunately, this product will not magically stop your neighbor's dog from barking. However, if your dog barks uncontrollably and disturbs guests or neighbors, you can patiently use this product to train and guide your dog.
