The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the gray wolf. Also called the domestic dog, it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the development of agriculture. 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 gustatory 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...)

Thirteen states of the United States have designated an official state dog breed. Maryland was the first state to name a dog breed as a state symbol, naming the Chesapeake Bay Retriever in 1964. Pennsylvania followed the year after, naming the Great Dane as its official breed. Dog breeds are mostly affiliated with the states that they originated in. North Carolina chose the Plott Hound as it was the only dog breed indigenous to the state.

Other official state dogs also are indigenous to their state, including the Boston Terrier (Massachusetts) and the Alaskan Malamute (Alaska). Pennsylvania selected the Great Dane not because of its origin, but because it was introduced by early settlers in the state to be used as a hunting and working dog; it was chosen over the Beagle, which was also proposed around the same time.
