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).
The Border Collie is extremely intelligent, with its keen, alert expression being a very important characteristic of the breed. Any aspect of structure or temperament that would impede the dog's ability to function as a herding dog should be severely faulted. The Border Collie is, and should remain, a natural and unspoiled true working sheep dog whose conformation is described herein. Honorable scars and broken teeth incurred in the line of duty are acceptable. Head Expression is intelligent, alert, eager, and full of interest.
