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 and are kept as pets. Border collies require considerably more daily physical exercise and mental stimulation than many other breeds.

Due to their working heritage, border collies are very demanding, playful, and energetic. They thrive best in households that can provide them with plenty of play and exercise, either with humans or other dogs.

Due to their demanding personalities and need for mental stimulation and exercise, many border collies develop problematic behaviors in households that are not able to provide for their needs. They are infamous for chewing holes in walls and furniture, and destructive scraping and hole digging, due to boredom.

Border collies may exhibit a strong desire to herd, a trait they may show with small children, cats, and other dogs. This trait has been deliberately encouraged, as it was in the dogs from which the border collie was developed, by selective breeding for many generations.
