Ultrasonic dog repellers are devices with a dubious reputation. Not thanks to physics - everything is fine with it. The problem is with sellers: they take advantage of people's fear of dogs and create unreasonably high expectations from repellers. But "miracle devices" are capable of producing exactly the same amount of benefit as an ordinary very loud sound.
Ultrasound is the name given to sound waves with a frequency exceeding 20,000 Hz. This threshold is officially accepted by science as the limit for the human ear. Statistics have shown that only unique people are capable of picking up higher frequencies among people. However, this range is quite common for dogs. If they have everything in order with their hearing, the Balls hear sounds with a frequency of up to 40,000 Hz. Cats are even bigger - up to 45,000 Hz. Therefore, our pets sometimes throw themselves up and look where we do not hear anything. The world beyond our perception is more than huge.
The idea behind an ultrasonic dog repeller is to "press on the psyche" of dogs with a loud sound that doesn't bother us. But a dog is not a frog that jumps in response to any stimulus. To understand its effect on tetrapods, remember how you react to a strong, unpleasant sound. If you are calm, step back. If annoyed, get angry more. If you are angry, you can not refrain from destructive actions. A dog is an intelligent animal that produces complex and often unpredictable reactions. With the difference from a human that she is less able to restrain herself.
A familiar dog handler, who trains service dogs and those whom they can pursue, begins his studies with people with approximately the following words:
Forget the saying 'A dog is a friend of man.' It is a predator with its own motivation for behavior. You are either a leader, or a competitor, or a prey for her. "
Ultrasonic Repeller Effectiveness Facts
After examining the reviews and watching videos of real, not fake users, we made the following conclusions.
- The degree of influence of the device depends on its power.
That is, on the number of decibels that it gives out. Which is logical. The problem is that they are inaudible, they are determined only by a special device and give a field for deception to manufacturers.
"In noisy places (for example, near a road), there is practically no effect."

- There are dogs with hearing impairment in the high frequency range
They age and their hearing deteriorates just like humans. And especially dangerous service dogs often work in extreme conditions, under shots.
"Some dogs do not pay attention, if you turn it on unnoticed, some stop approaching and look without fear, some retreat and continue to bark, some immediately stop barking and run away."

- In aggressive dogs, the device can cause increased hostility.
Field test videos of the repeller never show dog attack situations. Only peacefully minded, beaten by the life of the courtyard poor fellows. Whereas a calm trained dog reacts more often to a threat with an attack.
“The process is as follows: the dog runs, you poke it in the face with this daser, bewilderment appears in its eyes and it either runs away immediately or goes to the second circle. After the second lap, she snorts and walks off with a resentful look. The next day (if you go in the same place) she can still run up, but on the third day she already pretends that she does not notice you :) So in general it was quite dumb for the first time - the real effective range of the device is 2-3 meters (not 7 -10, as they say everywhere), that is, you have to stand, hold the button and believe that the device will work :)
And yet, I (and not only me) have the opinion that this all works only with mongrels who are just for fun (in the private sector and in industrial zones there are that is). If the dog runs at you with the intention to gobble up ... it will hardly help, I am sure that the dog can easily endure its effect if it really needs to bite you.Moreover, such a topic will not work if the dog is a fighting dog or you yourself are trying to attack it or climb into the territory it protects.

- The actual range is usually lower than the stated
Some manufacturers emphasize the compactness of their devices and their long range. What contradicts each other. Since the sound power directly depends on the diameter of the speaker.
- Dogs get used to repeated exposure to the repeller
There are railway tracks not far from our office. A flock of dogs lives near them. They lie quietly when a locomotive passes alongside the rumbling and screeching. Dogs can also learn to tolerate the hubbub of a repeller relatively staunchly.
Three recommendations for use
- Rule 1
The Repeller is good for unsuspecting yard dogs that bark at your window. To do this, he must have the required range. Powerful stationary models can be used to prevent intruders from wandering into your territory.
- Rule 2
With its help, you can keep at a distance one fearful, but evil-minded dog. In a flock, such animals, on the contrary, are able to provoke each other.
- Rule 3
Do not use it against calm trained dogs or any dog showing serious aggression.
