Additional information (Wiki): The Portuguese Water Dog, colloquially known as a PWD, is a breed of working dog as classified by the American Kennel Club. Portuguese Water Dogs are originally form the Portuguese region of the Algarve, from where the breed expanded to all around Portugal's coast, where they were taught to herd fish into fishermen's nets, to retrieve lost tackle or broken nets, and to act as couriers from ship to ship, or ship to shore. Portuguese Water Dogs rode in bobbing fishing trawlers as they worked their way from the warm Atlantic waters of Portugal to the frigid fishing waters off the coast of Iceland where the fleets caught cod to bring home.[1] Portuguese Water Dogs were also often taken with sailors, during the Portuguese discoveries.

Portuguese Water dogs make excellent companions. They are loving, independent, and intelligent and are easily trained in obedience and agility skills. Once introduced, they are generally friendly to strangers, and actively enjoy being petted, which, due to their soft, fluffy coats, is a favour that human beings willingly grant them.

Because they are working dogs, PWDs are generally content in being at their master's side, awaiting directions, and, if they are trained, they are willing and able to follow complex commands. They learn very quickly, seem to enjoy the training process, and have a long memory for the names of objects. They are generally considered too small to be used as service dogs or guide dogs for the blind, but they make unusually good therapy dogs and hearing dogs (assistance dogs for the deaf).

The PWD was a breed on the verge of extinction when, during the 1930s, Vasco Bensaude, a wealthy Portuguese shipping magnate, began to seek out fishermen's dogs and utilize them in a breeding program to re-establish the breed. Bensaude's kennel was named Algarbiorum, and his most famous dog was Leão (1931-1942), a very "type-y" fisherman's stud dog who was bred to so many different females that about half of the pedigreed Portuguese Water Dogs in existence can trace their lineage back to him. Bensaude was aided by two Portuguese veterinarians, Dr. Francisco Pinto Soares and Dr. Manuel Fernandes Marques. His work was carried on by Conchita Cintron de Castelo Branco, to whom he gave his last 17 PWDs and all his archives.
