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...)

A Sussex Spaniel with an undocked tail

The Sussex Spaniel is a breed of dog native to Sussex in southern England. It is a low, compact spaniel and is as old a breed as and similar in appearance to the Clumber Spaniel. They can be slow-paced, but can have a clownish and energetic temperament. They suffer from health conditions common to spaniels and some large dogs, as well as a specific range of heart conditions and spinal disc herniation.

The Sussex Spaniel was first recorded in 1795 in East and West Sussex, being at Goodwood and Rolvenden for specific hunting conditions. The breed nearly became extinct during the Second World War, but was bred back to sustainable numbers. It is now more popular in the United Kingdom and the United States than any other countries, and is recognised by all major kennel clubs. The breed was one of the first to be recognised by the UK Kennel Club in 1872. Sussex Spaniel Stump won the best in show in 2009 at the 133rd Westminster Kennel Club. (Full article...)

The American Eskimo Dog is a breed of companion dog originating in the United States (probably in New York City) in the twentieth century. It is derived from the German Spitz, the Finnish Spitz, and almost certainly the Pomeranian and Keeshond. The spitz family of Nordic dogs is one of the least altered by human husbandry and reflects most nearly the prototypical dog, from which stock all others have been derived. Archeology suggests that Neolithic dogs living with humans would today pass for spitzes.
