The Dogs Portal

The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it was domesticated from an extinct population of wolves during the Late Pleistocene, over 14,000 years ago by hunter-gatherers, prior to the development of agriculture. The dog was the first species to be domesticated by humans. Experts estimate that 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 Russian Spaniel is a type of spaniel first standardised in 1951 in the Soviet Union after World War II by cross breeding English Cocker Spaniels, English Springer Spaniels and other spaniel breeds. In 1951, the standard of the Russian spaniel was adopted, the selection of dogs for breeding began to be carried out in accordance with the requirements. Physically it is similar to a Cocker Spaniel, but has a shorter, tighter coat and a longer body. Developed and used as hunting dogs, this breed does not suffer from any major health complaints other than those normally associated with spaniels. It is the only gun dog breed originated in Russia. It is used for hunting game birds (marsh, field, upland and waterfowl birds) and hares. Popular in its native Russia, the breed was only introduced overseas in the 1990s, and is not yet recognised by any major kennel clubs, but is recognised by Russian Kynological Federation.

A coydog is a canid hybrid resulting from a mating between a male coyote and a female dog. Hybrids of both sexes are fertile and can be successfully bred through four generations. Similarly, a dogote is a hybrid with a dog father and a coyote mother. Such matings occurred long before the European colonization of the Americas, as melanistic coyotes have been shown to have inherited their black pelts from dogs likely brought to North America through the Bering Land Bridge 12,000 to 14,000 years ago by the ancestors of the indigenous peoples of the Americas.
