An ultrasonic dog repellant may seem like a simple solution to a big problem, but there are significant problems with the technology, and many people are moving on to a better solution. These devices use extremely high sound frequencies to provoke a response from the animal, but it’s not clear just how effective these devices are at doing that. There exists little research regarding the technology, and the Federal Trade Commission has only recently required manufacturers to back up their claims of effectiveness.
The problem with an ultrasonic dog repellant is that there is no reason to believe that canines are susceptible to extremely high sound frequencies. In fact, there is no confirmation that this approach works with any kind of animal, so when the device does work, it’s usually short lived. Higher frequencies are also harder to aim and cannot be detected by human ears, so others nearby will not be alerted as the device is used. And, of course, if the user can’t hear the device, they can’t know for sure that it’s working properly.
For these reasons, many people are switching over to audible technology, like the Sound Defense. Audible tones varying in unusual patterns are more likely to alarm or confuse an aggressive canine. This greatly improves the effectiveness of the device and is intended to better protect the user from a dangerous animal.
