Introduction

Collage of Nine Dogs.jpg

The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. "A man's best friend may have been domesticated about 15,000 years ago evolving" from the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.

Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species. Dogs vary widely in shape, size and colors. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, more recently, aiding disabled people and therapeutic roles. This influence on human society has given them the sobriquet of "man's best friend".

Selected article

Laika (from Russian: Лайка, "Barker", as well as a name of a dog breed) was a Russian space dog that became the first living creature from Earth to enter orbit. She was found as a stray wandering the streets of Moscow. Originally named Kudryavka, she was renamed Laika after her breed type. After undergoing training with two other dogs, she was selected to be the occupant of the Soviet spacecraft Sputnik 2 and was launched into space on November 3, 1957.

Laika died a few hours after launch from stress and overheating, likely due to a malfunction in the thermal control system. The true cause of her death was not made public until decades after the flight. Some former Soviet scientists have since expressed regret that Laika was allowed to die.

Although Laika did not survive the trip, the experiment proved that a living passenger could survive being launched into orbit and endure weightlessness. It paved the way for human spaceflight and provided scientists with some of the first data on how living organisms react to spaceflight environments.
