This is taken from our (Australian) standard.
HEAD
The head is wedge-shaped, proportionate in size to the body, (length of head about 40% of
height of withers) without being coarse or too elongated, in overall appearance dry and
moderately broad between the ears. The forehead is only slightly domed when viewed from
front and the side and without any or only slightly indicated central furrow.
The proportion of the skull to muzzle is 50%:50%. The breadth of the skull corresponds
approximately to its length. The skull (viewed from above) tapers evenly from the ears to the
nose with a sloping, not sharply defined stop, into the wedge shaped foreface (muzzle).
Upper and lower jaws are strongly developed. The top of the muzzle is straight, a dish faced
or convex curve is not desired. The lips are tight, well fitted and of a dark colour.
The nose must be black.
The dentition must be strong, healthy and complete (42 teeth conforming to the dentition
formula) the German Shepherd Dog has a scissor bite that is, the incisors must fit scissor-like
to each other so that the incisors of the upper jaw overlap those of the lower jaw in a scissor
fashion. Level, over or undershot bites are faulty, as well as large gaps between the teeth. It is
a fault when the incisors are placed in a straight line in the gums. The jawbones must be
strongly developed so that the teeth are embedded deeply in the gum line.
The eyes are of medium size, almond shaped, slightly oblique and not protruding. The colour
of the eyes should be as dark as possible. Light piercing eyes are not desirable as they detract
from the expression of the dog.
EARS
The German Shepherd Dog has erect ears of medium size that are carried upright and almost
parallel (not tilted inwards). They taper to a point and are set with the orifice to the front.
Tipped ears and drop ears are faulty. Ears carried laid back, during gaiting or when at rest are
not faulty.
NECK
The neck should be strong, and well muscled and free from throatiness (dewlap) the angle to
the body (horizontal) is approximately 45 degrees.
