Their imposing presence is marked by a muscular build and a massive head, setting them apart from medium-sized breeds such as Labrador Retrievers and German Shepherds. Unlike the more agile Border Collies or the compactly built Bulldogs, St. Bernards are known for their strength and size, which were essential traits for their historical role in alpine rescue missions. Their comparison with other breeds highlights the remarkable diversity in dog sizes, showcasing the St. Bernard’s unique position at the upper end of the scale.
