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...)

The Parson Russell Terrier is a breed of small white terrier that was the original Fox Terrier of the 18th century. The breed is named after the Reverend Jack Russell, credited with the creation of this type of dog. It is the recognised conformation show variety of the Jack Russell Terrier and was first recognised in 1990 in the United Kingdom as the Parson Jack Russell Terrier. In America, it was first recognised as the Jack Russell Terrier in 1997. The name was changed to its current form in 1999 in the UK and by 2008 all international kennel clubs recognised it under the new name.

A mostly white breed with either a smooth, rough or broken coat, it conforms to a narrower range of sizes than the Jack Russell. It is a feisty, energetic terrier, suited to sports and able to get along with children and other animals. It has a range of breed-related health issues, mainly relating to eye disorders.

The American Water Spaniel is a gundog breed of dog developed in the market hunting days of America's history. Hunters needed a dog that could function on land as well as in the marsh and that could easily fit into a canoe or skiff without taking up much room. An American original, this flushing spaniel also doubles as a competent retriever.

Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs have acquired the ability to understand and communicate with humans. Behavioral scientists have uncovered a wide range of social-cognitive abilities in domestic dogs. (Full article...)
