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 extinctPleistocene 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.
Belgian Shepherd varieties: Groenendael (1), Tervuren (2), Malinois (3) and Laekenois (4)
The Belgian Shepherd, also known as the Belgian Sheepdog or the Chien de Berger Belge, is a Belgian breed of herding dog of medium size. It is bred in four distinct varieties based on coat type and colour: the long-haired black Groenendael; the rough-haired fawn Laekenois; the short-haired fawn Malinois, and the long-haired fawn Tervuren. The American Kennel Club considers the four varieties to be separate breeds.
The breed descends from a common type of shepherd dog found throughout Western Europe that includes such modern breeds as the Bouvier des Ardennes, Dutch Shepherd and German Shepherd, and was a common sight in the service of Belgian shepherds for centuries. At the end of the nineteenth century a breed club was formed and attempts were made to standardise the breed. (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.
Old Jock (1859–1871), was a Fox Terrier famous during the late 19th and early 20th centuries. A mostly white dog, he ran briefly with a hunting kennel before becoming a show dog, most notably with a victory at the show which popularised the Fox Terrier. His main show rivalry was with a dog named Tartar, and along with a dog named Trap, the three were popular sires of the Fox Terrier breed. He was also involved in the early formation of the Jack Russell Terrier and the Dandie Dinmont Terrier breeds. (Full article...)
