We love our dogs, but sometimes, they get overexcited about something and start barking or acting aggressively. You may start yelling at your dog to be quiet. However, this may not work because it is not enough to capture the dog's attention. Having to deal with such a situation would be embarrassing for anyone. We have designed our device so that you can choose from three different modes for instant grabbing your dog's attention to stop unwanted behavior or train the dog to learn a new skill. The communication modes provided are safe for humans and dogs, and their diversity allows you to communicate with dogs in different situations and with dogs with different sensitivities to respond. It is important to understand that ultrasonic sound refers to sound waves that are higher in frequency than what humans are typically able to hear, which ranges from 20Hz to 20,000Hz. Our device is equipped with dual sensors to generate ultrasonic sound with a frequency of 25,000 Hz so that dogs, among smaller mammals, can hear it without disturbing humans. If dogs hear ultrasonic sounds, they will find them very annoying and stop in the middle of unwanted behavior like barking. This device offers an inexpensive and effective way to train your dog, but it is only as good as the trainer. To achieve positive and quick results, you must follow our guide: If your dog shows unwanted or negative behavior, push the button on your device, accompany it with a verbal correction, and immediately reward your dog once that behavior is stopped As the owner, you are responsible for deciding when to use the device. You must be consistent in your commands so the dog does not get confused. Therefore, you have to repeat the training process consistently until the dog permanently stops the unwanted behavior The process of training your dog might take some time, so keep practicing until your dog reaches the desired level of training
