Review on Weebo Pets Stainless Adjustable Frequency by Laura Washington

PROS: This whistle looks solid because of its all metal construction and the price was cheap because it is all metal which is why I bought this whistle over a whistle with plastic parts that wear out and/or break. easy. The chain is a nice touch as it makes it easier to wear and prevents the cap from getting lost. CONS: It is sold as an ultrasonic dog whistle and the description says so; "Use ultrasonic training your dog without words," so I expected him to be able to reproduce ultrasonic frequencies (frequencies above human hearing). No ultrasonic, just the usual whistle you see and hear in the movies used by the old London police. Use with an adjustable pitch function that is fully audible to humans. When the regulator is fully extended, the end cap will not even screw back on. Conclusion: I've tried this whistle on about a dozen dogs in the neighborhood and so far none of the dogs I've tried it on have really responded or stopped barking, they could take a look and then get back to what they were doing . My dog just ignores them completely. I'm going to shelve these as it's not even worth sending back to Revane and I recommend looking into another dog whistle that also emits ultrasonic frequencies. If you have ever tried an electronic bark deterrent, when you press the button there is no sound, but the dog still responds because it makes a sound that we cannot hear, but the dog hears it loud and clear. Just for your information. Wikipedia claims the following. how a real dog whistle should work: "To the human ear, a dog whistle only emits a soft hiss. [6] The advantage of a dog whistle is that it doesn't make a loud noise that irritates people but emits a regular whistle so it can be used to train or control animals without disturbing people nearby. Some dog whistles have adjustable sliders to actively control the frequency emitted. Trainers can use the whistle to simply get the dog's attention or inflict pain to change behavior."
