Newfoundlands, affectionately known as Newfies, are not only one of the biggest dog breeds, but they’re also one of the most docile and friendly. The breed originated in Newfoundland, Canada, where the dogs worked alongside fishermen and served as water rescue dogs. Because of this history, Newfoundlands are natural swimmers—their webbed paws allow them to cut through water, and their thick coat insulates them from frigid temperatures. You can still find working Newfoundland dogs today, but they also make a great family pet for those with enough space to house this gentle giant. The massive Newfoundland is a strikingly large, powerful working dog of heavy bone and dignified bearing. The sweet-tempered Newfie is a famously good companion and has earned a reputation as a patient and watchful 'nanny dog' for kids. The Newf head is majestic, the expression soft and soulful. The outer coat is flat and coarse. Colors are gray, brown, black, and a black-and-white coat named for artist Sir Edwin Landseer, who popularized the look in his paintings. The Newfie breed standard says that a sweet temperament is the "most important single characteristic of the breed." The Newf's sterling character is expressed in their affinity for kids. Trusting and trainable, Newfs respond well to gentle guidance. These noble giants are among the world's biggest dogs, and acquiring a pet that could outweigh you comes with obvious challenges. They also stand about 26–28 inches tall at the shoulder, have a thick double coat that sheds year-round, and tend to drool. Put all this together and you have a supersized dog that needs consistent upkeep. For pet parents dedicated to brushing their dog and wiping away drool, Newfoundlands reward you with their sweet temperament. These friendly dogs have a reputation for being calm at home, patient around children, and good roommates to other dogs and cats. The average Newfoundland dog lifespan is 9–10 years. While they’re a generally healthy breed, the Newfoundland’s size and genetics makes them susceptible to certain health conditions pet parents need to be aware of.
