The Border Collie comes in at number one. Because of their extraordinary intelligence and high energy, it is essential to give Border Collies an occupation or purpose, or you may well find your home wrecked upon your return from a long day at work. They have an intense connection with humans, making them ideal work and home companions. However, keep this in mind: Border Collies invariably will not do well unless they are with people who are as high energy as they are; they do best with humans who can participate in dog sports with them. Also, because of their background as herding dogs, they may be frustrated by small children, as their inability to herd the children as they deem fit is confounded. For the right human, the Border Collie is well behaved, exceptionally good at learning, and a true-blue companion.
