Labrador Retriever
Labradors are descended from dogs bred on the island of Newfoundland, in Canada. Its ancestor is the St. John's water dog, a breed that developed through breedings by early settlers of the island in the 16th century. These dogs were trained to bring in the fishing nets from the icy waters for the fishermen. In the early 19th century, they were brought to Poole in Great Britain. These dogs had short strong legs and were good swimmers. Their coats were thick and they had a broad tail.  Englishmen had many offers to buy them from fishermen because they were so attractive. The breed was instantly successful as a gun dog. The Earl of Malmesbury was interested and amazed by these dogs, and he started breeding them. He bred them for duck shooting on his estate. He established the new breed of retrievers, which he named Labrador.
