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 Pleistocene wolves over 14,000 years ago. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was 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...)

American Staffordshire Terrier at a dog show

The American Staffordshire Terrier, also known as the AmStaff, is a medium-sized, short-coated American dog breed recognized by the American Kennel Club, but not the United Kennel Club, which instead allows American Staffordshire Terriers to be registered under the American Pit Bull Terrier breed.

The height of an American Staffordshire Terrier is 18–19 in (46–48 cm) tall and weighs between 40–70 lb (18–32 kg). The American Kennel Club (AKC) describes the breed as "confident, smart and good-natured". American Staffordshire Terriers are not to be confused with American Pit Bull Terriers, though the American Pit Bull Terrier has similar ancestry they are two distinct breeds. It also should not be confused with the "Staffy" Staffordshire Bull Terrier of the United Kingdom. (Full article...)

Bluey is an Australian animated preschool television series which premiered on ABC Kids on 1 October 2018. The program was created by Joe Brumm and is produced by Queensland-based company Ludo Studio. It was commissioned by the Australian Broadcasting Corporation and the British Broadcasting Corporation, with BBC Studios holding global distribution and merchandising rights. The series made its premiere on Disney Junior in the United States and is released internationally on Disney+.

The show follows Bluey, an anthropomorphic six-year-old (later seven-year-old) Blue Heeler puppy who is characterised by her abundance of energy, imagination and curiosity about the world. The young dog 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 the focus on family, growing up, and Australian culture. The program was created and is produced in Queensland; its capital city Brisbane inspires the show's setting. (Full article...)
