BLUE OR GREY The called Blue or Grey Border Collie is due to the presence of a dilute gene, so the deepness of black color is blended, to bluish, slate or dark grey. As well as it happens with other coat colors, the differences are easily seen on puppies (better than on adults, whose coats gets darker).
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.
