Males normally weigh 65–80 kg (143–176 lb), and females 55–65 kg (121–143 lb), placing them in the 'Giant' weight range; but some Newfoundland dogs have been known to weigh over 90 kg (200 lb) – and the largest on record weighed 120 kg (260 lb) and measured over 1.8 m (6 ft) from nose to tail, ranking it among the largest of dog breeds. They may grow up to 56–76 cm (22–30 in) tall at the shoulder.The American Kennel Club (AKC) standard colours of the Newfoundland dogs are black, brown, grey, and white-and-black (sometimes referred to as Landseer). Other colours are possible but are not considered rare or more valuable. One was heavily built, large with a longish coat, and the other medium-sized in build – an active, smooth-coated water dog. The heavier breed was known as the Greater Newfoundland, or Newfoundland. The smaller breed was known as the Lesser Newfoundland, or St. John's dog.
