Chest of medium width reaching to the elbows, approximately 50% of the height at the withers. Ribcage oval and carried well back to strongly muscled loin. Flanks firm with underline moderately tucked up.

Gait/Movement:
Even, rhythmical gait, with forelegs extending well. Good drive from the rear. Covers the ground easily.
Coat:
Two varieties of coat: Medium and Long. Both have dense double coats with thick, abundant undercoat and hard, straight guard hairs. Hair on head, face, ears and legs shorter. At the neck and the back of the legs the coat is slightly longer. Slightly wavy, hard hair is allowed. In long coats, the hair at the neck forms a distinct mane, and at the back of the hindlegs forms trousers. The tail is bushy. Coat length never exaggerated.
Colour:
White. Dark skin desirable. Fawn colour on ear tips, back and upper part of tail undesirable.

Height at withers: Dogs 58-66cm (23-26ins); Bitches 53-61cm (21-24ins). Weight: Dogs 30-40kg (66-88lbs); Bitches 25-35kg (55-77lbs).
Faults:
Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog.
Note:
Male animals should have two apparently normal testicles fully descended into the scrotum.
