The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of wolves. Also called the domestic dog, it was selectively bred during the Late Pleistocene by hunter-gatherers. Dogs and the modern gray wolf share a common ancestor. Dogs were the first species to be domesticated over 14,000 years ago, before the development of agriculture, though genetic studies suggest the domestication process may have begun over 25,000 years ago. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.

Dogs have been bred for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and hearing, but inferior visual acuity. Dogs perform many roles for humans, such as hunting, herding, pulling loads, protection, companionship, therapy, aiding disabled people, and assisting police and the military.

Communication in dogs includes eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs), and chemical communication (scents, pheromones, and taste). They mark their territories by urinating on them, which is more likely when entering a new environment. Over the millennia, dogs have uniquely adapted to human behavior; this adaptation includes being able to understand and communicate with humans. As such, the human–canine bond has been a topic of frequent study, and dogs' influence on human society has given them the sobriquet of "man's best friend". (Full article...)

The Dalmatian is a breed of dog with a white coat marked with dark-coloured spots. Originally bred as a hunting dog, it was also used as a carriage dog by firefighters in the days of horse-drawn firehouse carriages. The origins of this breed can be traced to Croatia and the historical region of Dalmatia. It is thought that early ancestors of the breed were certain breeds of pointers and a spotted Great Dane. The modern breed has become a popular companion dog commonly entered by Dalmatian enthusiasts into kennel club competitions. (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.

A dog show is an animal show; it is an event where dogs are exhibited. A conformation show, also referred to as a breed show, is a kind of dog show in which a judge, familiar with a specific dog breed, evaluates individual purebred dogs for how well the dogs conform to the established breed type for their breed, as described in a breed's individual breed standard.

Dog shows can be in the means of evaluating dogs for breeding purposes. A conformation championship from a recognised national kennel club is generally considered as an indication of merit. Many breeders consider championships a prerequisite for breeding. Some critics argue that the shows can encourage selective breeding of traits and lower genetic diversity. (Full article...)
