Dogs have been known as man’s best friend for centuries, offering companionship, loyalty, and protection.
However, not all dog breeds are equally suited for every environment.
Some breeds are more prone to aggressive behavior due to their natural instincts, size, or strength, making them more aggressive when not properly trained or socialized.
While no breed is inherently “bad,” understanding the potential risks associated with certain dog breeds is essential for both owners and the public.

This guide will provide insights into their size, temperament, and how to handle them safely.
