One of the most popular family companions, the Labrador once used to work on the Newfoundland coast retrieving the cork floats of fishing nets and swimming them ashore so that fishermen could pull in the fish-filled nets. Although a few of this breed suffer from health or temperamental problems the Labrador epitomises all the ideal features of a Canine member of the human family. It is one of the most loyal and dependable breeds in the world. It is used extensively as a guide dog for the blind. It weighs 25-34 kgs and is about 54-57 cms tall. The colours maybe yellow, brown (chocolate) or black coloured.
