Comparing Different Types Of Dog Repellers

Many dog repellers have been marketed to outdoors people over the years, promising to keep runners and bikers, among others, safe from an animal attack. The threat is real, as a canine bite can cause serious injury, especially if it comes from a larger breed. Some breeds are capable of creating hundreds of pounds of bite pressure, and this is enough to destroy bone and other tissues. If someone goes to the ground while they are being attacked, the animal will often lash out at the victim’s face, possibly disfiguring them or killing them outright with a single strike. Unfortunately, there’s really no way to predict when an animal will attack, and the victim will usually have mere seconds to respond. What they do in those seconds will determine whether they walk away unscathed or have to be rushed to a hospital.

How effective are dog repellers?

It depends on the device because there are a variety of methods in stopping an attacking animal. For many years, the only option was a spray canister loaded with an irritant. Such devices are functionally identical to handheld pepper spray canisters that many people use in self-defense. For obvious reasons, though, sprays tend to work better on people than on animals. Attacking canines are much more mobile, smaller, and attack using their teeth, so there is an extremely tiny window of opportunity for the victim to engage the spray. Worse, inclement weather like the wind or heavy rain will render these dog repellers ineffective, as it will be nearly impossible to aim and fire. In high winds, the user may debilitate themselves with a spray as it blows back into their face.

Most people, or at least those particularly concerned with their safety, have moved on to ultrasonic dog repellers, but there are issues with those as well. Ultrasonic devices emit frequencies beyond the range of human hearing, but within the animal’s perceptible range. The thinking being, the higher pitched the noise is, the more annoying it’s likely to be to the animal and the greater the chance that it will halt them. Ultrasonic devices, though, do not engage the sensitive part of the canine’s hearing, and ultrasonic frequencies are difficult to aim, given their narrow beam width. And while such devices usually come with some kind of indicator that alerts the user when the device is working, there’s no way for a human to know for sure. That is because the device is outside the human’s hearing range.

The newest method in dog repellers is to use audible sound frequencies instead, which is the concept behind the Sound Defense. The Sound Defense produces a variety of tones audible to both canine and human alike, and the pattern in which they emit is alarming to the animal. Confusion and intimidation are what the Sound Defense produces, and an attacking animal will usually break off pursuit in under a second. That’s because the Sound Defense engages the sensitive part of the animal’s hearing.

And with its wider beam angle, the Sound Defense is much easier to aim and use. When a victim only has a few seconds to think and act, this may be the deciding factor.
