Border Collie
The Border Collie is a working and herding dog breed developed in the Scottish borders for herding livestock, especially sheep. It was specifically bred for intelligence and obedience.
Considered highly intelligent, extremely energetic, acrobatic and athletic, they frequently compete with great success in sheepdog trials and dog sports. They are often cited as the most intelligent of all domestic dogs. Border Collies continue to be employed in their traditional work of herding livestock throughout the world.
Description.
In general, Border Collies are medium
without tiring, even over very rough or steep ground. Working collies display a keen intelligence for the job at hand and are instinctively highly motivated. They are often intensely loyal. Dogs of collie type or derivation occupy four of the first sixteen ranks in Stanley Coren's "The Intelligence of Dogs", with the Border Collie being first. These characteristics generally make working strains suitable for agility; in addition to herding work they are well suited to active sports such as sheepdog trials, flyball, disc dog and dog agility.
