Dog breed developed in Newfoundland, possibly from crosses between native dogs and the Great Pyrenees dogs that Basque fishermen introduced into North America in the 17th century. Noted for sea rescues, the gentle, patient Newfoundland stands 26–28 in. (66–71 cm) and weighs 110–150 lbs (50–68 kg). Powerful hindquarters, a large lung capacity, large webbed feet, and a heavy, oily coat enable it to swim in cold waters. It has also been used as a watchdog and draft animal. The typical Newfoundland is solid black; the Landseer Newfoundland is usually black and white.
