Guard dogs are specially trained canines that help protect property, people, and assets. They are often used in various settings, including homes, businesses, and military operations. These dogs are selected for their natural protective instincts and are trained to respond to threats, deter intruders, and alert their handlers. Common breeds used as guard dogs include German Shepherds, Rottweilers, and Doberman Pinschers. Training typically involves obedience, socialization, and specific protection techniques. Proper training ensures that guard dogs can distinguish between normal and threatening situations, making them effective in their roles while remaining safe and controlled around family and friends.
