<P> The Newfoundland's extremely large bones give it mass, while its large musculature gives it the power it needs to take on rough ocean waves and powerful tides . These dogs have huge lung capacity for swimming extremely long distances and a thick, oily, and waterproof double coat which protects them from the chill of icy waters . The double coat makes the dog hard to groom, and also causes a lot of shedding to occur . The droopy lips and jowls make the dog drool, especially in high heat . </P> <P> In the water, the dog's massive webbed paws give it maximum propulsion . The swimming stroke is not an ordinary dog paddle . Unlike other dogs, the Newfoundland moves its limbs in a down - and - out motion giving more power to every stroke . </P> <P> The Newfoundland dog is known for its calm and docile nature and its strength . They are highly loyal and make ideal working dogs . It is for this reason that this breed is known as "the gentle giant". International kennel clubs generally describe the breed as having a sweet temper . It typically has a deep bark and is easy to train if started young . They are wonderfully good with children, but small children can get accidentally leaned on and knocked down . Newfoundlands are ideal companions in the world of therapy and are often referred to as the nanny dog . The breed was memorialized in "Nana", the beloved guardian dog in J.M. Barrie's Peter Pan . The Newfoundland, in general, is good with other animals, but its size can cause problems if it is not trained . </P> <P> There are several health problems associated with Newfoundlands . Newfoundlands are prone to hip dysplasia (a malformed ball and socket in the hip joint). They also get Elbow dysplasia, and cystinuria (a hereditary defect that forms calculi stones in the bladder). Another genetic problem is subvalvular aortic stenosis (SAS). This is a common heart defect in Newfoundlands involving defective heart valves . SAS can cause sudden death at an early age . It is similar to having a heart attack . It is common that "Newfs" live to be 8 to 10 years of age; 10 years is a commonly cited life expectancy . But, Newfoundlands can live up to 15 years old . </P>
