Just because a dog is small doesn’t mean they’re delicate. Some of the tiniest breeds in the world have more toughness and resilience than dogs five times their size. These little powerhouses may fit comfortably in your lap, but their personalities and determination make them anything but fragile. These dogs have courage, endurance, and an undeniable never-back-down attitude. Some of them have a high pain tolerance, others have the bravery of a lion, and a few of them seem to believe they are big dogs trapped in small bodies.
