[Play with your dog] A dog whistle is an excellent tool for communicating with your dog. You need patience, and you will feel immense joy when your dog finally understands your commands and performs the corresponding actions. [Not ultrasonic, audible to the human ear] The purpose of a dog whistle is to facilitate training. Only through training can a dog understand your commands and respond accordingly. There is no magic dog whistle in the world that can make a dog do anything. [Rewards and guidance are good ways to train your dog] When your dog exhibits the correct behavior under our guidance, it should receive appropriate rewards to confirm that it is following its owner's commands or supporting the owner's actions. We introduce training methods here for your reference. [Roughly intervening in your dog's behavior is not advisable] If you want your dog to stop barking, roughly prohibiting it or using an ultrasonic whistle is not a good method. The dog will only feel confused and may even become more irritated. [Are you worried about your neighbor's dog barking?] Unfortunately, this product cannot magically make your neighbor's dog stop barking. However, if your dog barks for no reason and disturbs guests or neighbors, you can patiently use this product to train and guide your dog.
