Even those who don't have pets know that miniature-looking dogs can sometimes be meaner than giants.
Such babies often show aggression even towards members of their own family, not to mention strangers and animals.
There are many reasons why this happens, and one of them is the Napoleon complex.
According to one version, small dogs behave aggressively in an attempt to protect themselves.
This version, although not scientifically confirmed, is nevertheless found in the wild, for example, when sparrows attack crows, and pumas attack bears.
Predators attacked by the "little ones" try to avoid such clashes, since even a small injury can lead to death.
Another reason why "small fry" keep larger animals at bay is that small animals are flexible and agile, which means they can cause serious injury.
Here is the answer to the question of why small dogs are so angry - with their open aggression or compensating for their small size by using noise and growling to drive away larger relatives (and not only).
