Sometimes situations arise when a person’s cute friends can pose a serious danger: for example, during the mating season, they gather in packs (the so-called “dog weddings”) or the dog was unlucky with the owner, and from a cheerful friendly puppy he raised an insecure, unloved, and therefore the beast embittered by the whole world. At the same time, no matter how much a person imagines about himself, we are powerless in front of an angry animal, no matter how large it is. We do not have claws and teeth to give a worthy rebuff, but we have a mind that made it possible to invent protective technical means. And one of them is electronic dog repellents, which are safe for both humans and four-legged aggressors.
