The Newfoundland comes from the island of Newfoundland, where fishermen relied on it to haul nets, pull carts and work in cold water. Webbed feet and a thick, water-resistant double coat make it a strong swimmer, and its sweet, devoted nature earned it the nickname "nanny dog." Most adults weigh 100 to 150 pounds and come in black, brown, gray or black-and-white.
In Dallas, that coat is the main thing to plan around. Newfoundlands shed heavily, drool, and tolerate heat poorly, so air conditioning and a plan for hot afternoons matter more than a big yard. Dogs vary, and some are mellower or mouthier than others. Expect giant-breed food and vet bills, and a lifespan of roughly 8 to 11 years.
