Long before modern weapons and advanced technology, armies marched into battle with loyal dogs at their sides. From the battlefields of ancient Egypt to the disciplined legions of Greece and Rome, these remarkable animals were trained to guard camps, charge enemies, and protect their handlers with unwavering bravery.
