Border collies require considerably more daily physical exercise and mental stimulation than many other breeds. The border collie is widely considered to be the most intelligent dog breed. The border collie ranks 1st in Stanley Coren's The Intelligence of Dogs, being part of the top 10 brightest dogs. In nearly every region of the world, the border collie is now also a breed that is shown in ring or bench shows. For the people who participate in these events, the Border Collie is defined by the breed standard, which is a description of how the dog should look. In New Zealand and Australia, where the breed has been shown throughout most of the twentieth century, the Border Collie standards have produced a dog with the longer double coat (smooth coats are allowed), a soft dark eye, a body slightly longer than tall, a well-defined stop, semi-pricked ears, as well as a gentle and friendly temperament. This style of Border Collie has become popular in winning show kennels around the world, as well as among prestigious judges.
