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...)

Blenheim Cavalier King Charles Spaniel

The Cavalier King Charles Spaniel (CKCS) is a British breed of toy dog of spaniel type. Four colours are recognised: Blenheim (chestnut and white), tricolour (black/white/tan), black and tan, and ruby; the coat is smooth and silky. The lifespan is usually between eight and twelve years.

The Cavalier King Charles changed dramatically in the late seventeenth century, when it was inter-bred with flat-nosed breeds. Until the 1920s, it shared the same history as the smaller King Charles Spaniel. Breeders attempted to recreate what they considered to be the original configuration – a dog resembling Charles II's spaniel of the English Civil War period, when supporters of the king were known as Cavaliers.

A therapy dog is a dog that is trained to provide affection, comfort and support to people, often in settings such as hospitals, retirement homes, nursing homes, schools, libraries, hospices, or disaster areas. In contrast to assistance dogs, which are trained to assist specific patients with their day-to-day physical needs, therapy dogs are trained to interact with all kinds of people, not just their handlers.
