The dog or domestic dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf, characterized by an upturning tail. The dog is derived from an ancient, extinct wolf, and the modern wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by hunter–gatherers over 15,000 years ago, 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 Basenji (/bəˈsɛndʒi/) is a breed of hunting dog. It was bred from stock that originated in central Africa. The Fédération Cynologique Internationale places the breed in the Spitz and primitive types. The Basenji produces an unusual yodel-like sound, due to its unusually shaped larynx. This trait also gives the Basenji the nickname the 'barkless dog.'

Basenjis share many distinctive traits with pariah dog types. Basenjis come into estrus only once annually similar to dingoes and New Guinea singing dogs, when compared with other dog breeds which may have two or more breeding seasons each year. Basenji lack a distinctive odor, and are prone to howls, yodels, and other vocalizations over the characteristic bark of modern dog breeds. The breed's original foundation stock came from the Democratic Republic of the Congo. (Full article...)

Retrievers, such as this Labrador Retriever, are a type of gun dog bred to retrieve downed birds from water or land. Although spaniels and some pointing breeds routinely retrieve game, retrievers are skilled in finding game, and 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. A soft mouth refers to the willingness of the dog to carry game without damaging it. Retrievers are often selected as family pets, and many suburban dogs end up retrieving newspapers and sticks like this dog.
