Muscle, courage, instinct. These words perfectly define the strongest dog breeds that have captivated humans for centuries. Some dogs are built for speed. Some are designed to pull, guard, and protect. Others are born to hunt and defend.
Throughout history, dogs have played crucial roles alongside humans. They helped with hunting, guarded livestock, and worked tirelessly in harsh conditions.
