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 extinct gray wolves, and 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 mustard colour of the Dandie can be any shade including and between reddish brown and fawn.

A Dandie Dinmont Terrier is a small Scottish dog breed in the terrier family. The breed has a very long body, short legs, and a distinctive topknot of hair on the head. They are friendly but tough, and are suitable for interaction with older children. There are breed-specific health concerns: they can be affected by spinal problems due to their elongated body, and the breed is affected by canine cancer at a higher than average rate.

The breed is named after a fictional character in Sir Walter Scott's novel, Guy Mannering. This character, Dandie Dinmont, is thought to be partly based on James Davidson, who is credited as the originator of the modern breed. Davidson's dogs descended from earlier terrier-owning families, including the Allans of Holystone, Northumberland. (Full article...)

Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body, and weighed only 113 grams (4.0 oz). The heaviest dog was an English Mastiff named Zorba, which weighed 314 pounds (142 kg). The tallest known adult dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder. (Full article...)
