Dogs are known for their loyalty and companionship, but not all breeds are equally friendly towards strangers. Some breeds naturally tend to be wary, reserved, or protective regarding unfamiliar people. This wariness often stems from their breeding history, where they were developed to guard property, livestock, or human families.
