The border collie is often regarded as one of the most intelligent dog breeds in the world. They are often used as a herding dog, but can also do anything you show them. Typical traits of this breed include driven, athletic, acrobatic, and energetic. If you do not keep them busy, they would do some destructive behaviors. [10]
