The Newfoundland is a giant working dog from the Canadian island of the same name, bred to haul nets and pull people from cold Atlantic water. Adults usually weigh 100 to 150 pounds and wear a thick, water-resistant double coat in black, brown, gray or the black-and-white Landseer pattern. They're known for a sweet, patient nature, and many are gentle with children and friendly with visitors, though each dog varies.
That cold-water coat is the main thing to weigh in the Valley, where highs top 100°F from June through September. A Newfie here needs indoor air conditioning, shade, and exercise at the edges of the day. Expect heavy shedding, plenty of drool, giant-breed bills and a lifespan often around 8 to 11 years. Early manners training matters before a puppy outgrows you.
