Bearded Collie

Bearded Collies, originating in Scotland as herding dogs, are intelligent and have a high need for exercise. They can also be a bit stubborn, so it's important to start obedience training at an early age and be consistent with them. They prefer space to run off-leash and need a lot of attention to develop.
