A brief overview as to why we 'Hip
Score' German Shepherd Dogs before we breed.
Dog hip dysplasia is a common
skeletal developmental problem generally found in larger dogs and,
in particular, in working and sporting dog breeds. Dog hip
dysplasia occurs because the
upper ball portion of the dog's hind legs doesn't fit properly into
the hip socket, causing instability within the ball-and-socket
joint, which in turn eventually causes the hip bone to tear apart
thus being called dog hip dysplasia.
At this point in time, no one knows exactly what causes dog hip
dysplasia, but most vets now agree that dog hip dysplasia is
probably an inherited condition. They also agree that the dog
hip dysplasia probably isn't influenced by a dog's diet, although
dog hip dysplasia is aggravated by excessive weight and obesity
problems. They suspect that the animal's overall weight and/or very
rapid growth during puppy hood may be contributing factors for dog
hip dysplasia.
SYMPTOMS:
While dog hip
dysplasia have no apparent symptoms, others, however, have varying
degrees of lameness and arthritic pain. In the most severe cases,
dog hip dysplasia can cause joint deterioration, limiting the dog's
mobility. As the condition evolves, dog hip dysplasia becomes quite
painful and may be more pronounced on cold, damp days. Typical
symptoms of dog hip dysplasia include: lameness, especially after
prolonged exercise, a waddling or swaying gait, difficulty in rising
or climbing stairs, reluctance to move, changes in temperament, pain
when hips move, poorly developed musculature in the hind quarters
and the weight-carrying legs.

The
current BVA/KC
scoring scheme for hip dysplasia (HD) has
been in operation since 1984 and since then
over 100,000 X-rays have been assessed.
Dysplasia means abnormal development, and
the degree of hip dysplasia present is
indicated by a score assigned to each hip.
The hip score is the sum of the points
awarded for each of nine aspects of the
X-rays of both hip joints. The minimum hip
score is 0 and the maximum is 106 (53 for
each hip).
The lower the
score the less the degree of hip dysplasia
present.
An average (or
mean) score is calculated for all breeds
scored under the scheme and advice for
breeders is to use only breeding stock with
scores well below the breed mean score.
The minimum age
for hip scoring is one year, and each dog is
only ever scored once under the scheme.
