Newfoundlands have webbed feet and a water-resistant coat. Males weigh 60–70
kg (130–150 lb), and females 45–55 kg (100–120 lb), placing them in the "giant"
Most Newfoundlands are black, but brown, gray (very rare), Irish Spotted (black with white markings), and Landseer (black head, white body with black markings) varieties exist. The Landseer is named after the artist Sir Edwin Landseer, who featured them in many of his paintings. Some kennel clubs consider the Landseer to be a separate breed; others consider it simply a Newfoundland color variation. Some kennel clubs consider Irish Spotted to be an "invalid" marking, and these clubs will not allow them to be shown.
