Height at the withers to length of body: 9 to 10. Depth of chest is nearly 50% of height at withers.

As a family dog, the Leonberger is an agreeable partner for present day dwelling and living conditions, who can be taken anywhere without difficulty and is distinguished by his marked friendliness towards children. He is neither shy nor aggressive. As a companion, he is agreeable, obedient and fearless in all situations of life. The following are particular requirements of steady temperament:

On the whole deeper than long and elongated rather than stocky. Proportion of muzzle to skull region about 1 to 1. Skin close fitting all over, no wrinkles.

Skull : In profile and seen from front, slightly arched. In balance with body and limbs, it is strong but not heavy. The black part of the skull is not substantially broader than near the eyes.
Stop : Clearly recognisable but moderately defined.

Nose : black.
Muzzle : Rather long, never running to a point; nasal bridge of even breadth, never dipped, rather slightly arched (roman nose).
Lips : Close fitting, black, corner of lips closed.
Jaws/Teeth : Strong jaws with perfect, regular and complete scissor bit, in which the upper teeth close over the lower without any gap and the teeth are placed vertically in the jaw, with 42 healthy teeth, according to usual tooth formula (missing M3 tolerated). Pincer bite is tolerated; no constriction of canines in lower jaw.
Cheeks : Only moderately developed.
Eyes : Light brown to as dark brown as possible, medium size, oval, neither deep set, nor protruding, neither too close together nor too wide apart. Eyelids close fitting, not showing any conjunctiva. The white of the eye (the visible part of the sclera) not reddened.
Ears : Set on high and not far back, pendant, medium size, hanging close to head, fleshy.

Flowing without break to the withers in a slight curve. Long rather than stocky, without throatiness or dewlap.

Withers : Pronounced, specially in males.
Back : Firm, straight, broad.
Loins : Broad, strong, well muscled.
Rump : Broad, relatively long, gently rounded, flowing to merge with tail set on; not in any way overbuilt.
Chest : Broad, deep, reaching at least to height of elbows. Not too barrel shaped, more oval.
Lower profile : Only lightly tucked up.

Very well furnished; while standing, it hangs down straight; also in movement it is only slightly curved and preferably should not be carried above the prolongation of the topline.

Legs : Straight, parallel and not too close.
Shoulder/Upper arm : Long, sloping, forming a not too blunt angle, well muscled; elbows close fitting.
Pastern : Strong, firm; straight, seen from front. Almost vertical seen from side.
Forefeet : Straight position (turning neither in nor out), rounded, tight, toes well arched; black pads.

Legs : Position when seen from rear, not too close, parallel.
Hocks and feet : Turned neither in nor out. Dewclaws: Must be removed.
Pelvis : Slanting position.
Upper thigh : Rather long, slanting, well muscled. Upper and lower thigh form a distinct angle.
Hocks : Strong, distinct angle between lower thigh and rear pastern.
Feet : Standing straight, only slightly longish. Toes arched, pads black.

Ground covering even movement in all gaits. Extending well in front, and good drive from hindquarters. Seen from front and behind limbs move in a straight line when walking or trotting.

Coat

Medium soft to coarse, profusely long, close fitting, never with a parting, letting the form of the whole body be seen despite the thick undercoat. Straight, slight wave still permitted; forming a mane on neck and chest, specially in males; distinct feathering on front legs and ample breeches on hind legs.

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

• Shy and aggressive dogs.
• Severe anatomical faults (i.e. pronounced cow hocks, pronounced roach back, bad swayback; front feet turning out extremely. Totally insufficient angulation of shoulder, elbow, stifle or hock joints.
• Brown nose leather.
• Very strong lack of pigment in lips.
• Absence of teeth (with the exception of M3). Over- or undershot or other faults in mouth.
• Eyes without any brown.
• Entropion, ectropion.
• Distinct ring tail or too highly curled up tail.
• Brown pads.
• Cords or strong curls.
• Faulty colours (brown with brown nose and brown pads; black and tan; black; silver; wild-coat colour).
• Complete lack of mask.
• Too much white (reaching from toes onto pasterns), white on chest larger than palm of hand, white in other places).

N.B. : Male animals should have two apparently normal testicles fully descended into the scrotum.
