Dogs have incredible hearing so this whistle makes for an effective training tool. They can hear sounds up to four times farther away than we can, as well as sounds that travel at a much higher frequency.
This silent dog whistle emits sounds at an ultrasonic frequency that your dog is able to hear but to you or I it simply sounds like air escaping through a small hole, ensuring that your pooch will hear the sound from far away and your neighbours will not.
Made of high quality metal, solid and durable.
Dimensions: 9cm x 0.8cm
