The Dogs Portal

The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinct Pleistocene wolf; the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.

The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. Over the millennia, dogs became uniquely adapted to human behavior, and the human–canine bond has been a topic of frequent study. This influence on human society has given them the sobriquet of "man's best friend". (Full article...)

The Marquesan Dog or Marquesas Islands Dog is an extinct breed of dog from the Marquesas Islands. Similar to other strains of Polynesian dogs, it was introduced to the Marquesas by the ancestors of the Polynesian people during their migrations. Serving as a tribal totems and religious symbols, they were sometimes consumed as meat although less frequently than in other parts of the Pacific because of their scarcity. These native dogs are thought to have become extinct before the arrival of Europeans, who did not record their presence on the islands. Petroglyphic representations of dogs and the archaeological remains of dog bones and burials are the only evidence that the breed ever existed. Modern dog populations on the island are the descendants of foreign breeds later reintroduced in the 19th century as companions for European settlers. (Full article...)

Although spaniels and some pointing breeds routinely retrieve game, and many retrievers are skilled in finding game, retrievers are distinguished in that non-slip retrieval is their primary function. As a result, retriever breeds are bred for soft mouths and a great willingness to please, learn, and obey. Poodles, though developed as hunting dogs, are most commonly used as companions.
