Ultrasonic Dog Whistle

How the ultrasonic dog whistle works Everyone knows that dogs have much more developed hearing than us humans: while a person is unable to perceive some sounds, dogs perceive them perfectly. While the human ear can hear sounds at frequencies of up to 20 kHz, our canine friend's ear, depending on size, breed and age, can hear sound frequencies ranging from 20 kHz to 60 kHz. Therefore, it is important to set your Dog's Ultrasonic Whistle to the correct frequency that suits his hearing. You can proceed as follows: test the whistle while the dog is sleeping. If the sound doesn't cause any reaction, adjust your waist slightly and whistle again. If there is no reaction this time, persist by changing the frequency of the sound again until the dog hears it and wakes up. At this point, close the locking screw to keep the whistle calibrated. ANDIs it true that the ultrasonic dog whistle is harmful? Let's start from this consideration: the whistle's ultrasounds do not cause any disturbance to your dog. Fido will easily learn to perceive the modulation of the sound and will associate it with a specific command that he knows he must carry out. Our whistles are professional and made so that their use does not cause any type of suffering to dogs, and are designed to emit frequencies that do not hurt their ears and do not damage them in any way. If used correctly and without abuse, the whistle is able to comply with all current regulations.Main Features of the Ultrasonic Dog Whistle: Equipped with Adjustable Intensity of 53 mm Ultrasonic transmission Does not damage the dog and its hearing in any way
