at least to the hock. The ideal tail carriage is low when the dog is concentrating on a given task and may have a slight upward swirl at the end like a shepherd's crook. In excitement it may be raised, but the base of the tail should not curve forward over the back.
Forequarters: Forelegs should be parallel when viewed from front, pasterns slightly sloping when viewed from side. Because sufficient length of leg is crucial for the type of work the breed is required to do, the distance from the wither to the elbow is slightly less than from the elbow to the ground. The shoulder blades are long and well laid back. Shoulder blades and upper arms are equal in length and meet in a right angle as nearly as possible. The prosternum is easily felt but not pronounced. There is sufficient width between the tops of the shoulder blades to allow for the characteristic crouch when approaching and moving stock. The elbows are neither in nor out. Feet are compact, oval in shape; pads deep and strong, toes moderately arched and close together with strong nails of moderate length. Dewclaws may be removed.
Hindquarters: Broad and muscular, in profile sloping gracefully to the low set tail. The thighs are long, broad, deep and muscular. Stifles are well turned with strong well let down hocks. Proper length of hock is approximately one-quarter to one-third the height of the dog. When standing with the hocks perpendicular to the ground the toes of the rear feet should be in line with the point of buttock. Rear feet should be parallel, but may toe out slightly when freestanding. Feet are compact, oval in shape; pads deep and strong, toes moderately arched and close together with strong nails of moderate length. Dewclaws should be removed.
Coat: Two varieties are permissible, both having close-fitting, dense, weather resistant double coats with the top coat either straight or slightly wavy and coarser in texture than the undercoat which is soft, short and dense. The rough variety coat may vary in length without being excessive. Proper texture is more important than length. Forelegs, haunches, chest and underside are feathered and the coat on face, ears, feet, fronts of legs is short and smooth. The smooth variety is short over entire body, is usually coarser in texture than the rough variety and may have slight feathering on forelegs, haunches, chest and ruff. Neither coat type is preferred over the other. Seasonal shedding is normal and must not be penalized. Excess hair on the feet, hock and pastern areas may be neatened for the show ring. Whiskers are untrimmed. Dogs should be presented naturally, without excessive trimming or sculpting.
Color: The Border Collie appears in all colors or combination of colors and/or markings. All colors are to be judged equally with no one color or pattern preferred over another. White markings may be clear white or ticked to any degree. Random white patches on the body are permissible but should not predominate. The predominant ear color should match the primary body color. Color and markings are always secondary to physical evaluation and gait.
Gait: The Border Collie is an agile dog, able to suddenly change speed and direction while maintaining balance and grace. Endurance is its trademark. The head is carried level with or slightly below the withers. When shown, Border Collies should move on a loose lead and at moderate speed, never raced around the ring with the head held high. When viewed from the side the trot covers the ground effortlessly with minimum lift of feet. The topline is firm with no roll or bounce. Front reach and rear drive are symmetrical, with the front foot meeting the ground directly under the nose and the rear foot pushing back without kicking up. When the rear foot is coming forward, it should reach to the spot just vacated by the front foot. Viewed from the front, action is forward and true without wasted motion. Viewed from the rear, hindquarters drive with thrust and flexibility with hocks turning neither in nor out, moving close together but never
