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...)

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.

Bluey is an Australian animated television series aimed at preschool children, created by Joe Brumm and produced by Ludo Studio in Queensland. It was commissioned by the Australian Broadcasting Corporation and the British Broadcasting Corporation, with BBC Studios holding global distribution and merchandising rights. Bluey premiered on ABC Kids on 1 October 2018. It subsequently made its international debut on Disney Junior in the United States and is available for streaming on Disney+.

The show follows Bluey, an anthropomorphic six-year-old (later seven-year-old) Blue Heeler puppy who is full of energy, imagination, and curiosity about the world. She lives with her father, Bandit; mother, Chilli; and younger sister, Bingo, who regularly joins Bluey on adventures as the pair embark on imaginative play together. Other characters featured each represent a different dog breed. Overarching themes include family life, growing up, and Australian culture. Brisbane, the state capital of Queensland, inspired the show's setting. (Full article...)
