The Border Collie comes in two coat varieties: rough or smooth. Both varieties are double coat and weather resistant and are close fitting and thick. The outer coat is either wavy or straight and coarse in texture. The under coat is dense, short, and soft. The rough coat variety has fur of medium length.
They're different dog breeds. Border collies are the smartest dog breed and the most common color is black and white but can also be brown and white. Both are great herd â¦ ing dogs but border collies are the best herding dogs because of their intelligence. Border collies also need a job to be happy. Both dogs are good but I strongly recommend a border collie if you have a job for it to do. They're both loyal, cute, and smart dogs.
