When it comes to ultrasonic dog repeller technology, a thorough review of the science behind it has never been established. What meager research does exist was primarily conducted on insects and rodents, and both are a long way from canines. There are some concerns with the technology’s effectiveness, and though it has been the subject of several studies, the conclusion is that there is no conclusion. Whether or not it works is still an open question.
That’s why it is best to look at what consumers are doing instead, and many are switching to something other than an ultrasonic dog repeller. A review of the technology brings up several concerns. It is difficult to aim, as it emits a narrow width sound beam. It is impossible to know if it’s working or not, and impossible to know just what sounds it is emitting. When activated, it doesn’t alert other people to the threat. But most of all, there’s no way of knowing if the device is operating in the canine’s sensitive hearing range and capable of deterring the animal. At least, not until it is used on an attacking canine.
That’s why more and more people are switching to devices that produce audible sounds instead. These devices are easier to aim and produce immediate feedback for the user and the people around the user. They also use many sounds in unique pattern, increasing the chances that the device will trigger a response in the animal. It’s a deterrence method that just makes more sense, and the results speak for themselves.
