Hip dysplasia is unfortunately found in almost all breeds,
especially the larger ones.
The Leonberger is no exception. Hip
dysplasia (HD) is an hereditary developmental disease.
HD is a
result of abnormal development of the "ball-and socket"
joints of the hips.
Severity covers a wide range from slight
abnormality to very severe dislocation.
Dysplastic dogs are born
with normal hip joints which undergo changes as the dogs mature.
Although the cause is hereditary, the disease can be made worse
by environmental factors such as rapid growth, overfeeding and
Keeping the incidence of the disease to a
minimum depends on accurate X-ray diagnosis, accurate breeding
records and strict breeding regulations.
The national Leonberger clubs have been extremely diligent in
education and enforcement of breeding regulations designed to
minimize dysplasia in Leonbergers. Leonbergers are not allowed to be
bred in most countries, without certification that the parent's
have hipscores are within the range of the club's breeding rules.
Different countries have different scales for reporting the
results of veterinary examination of X-rays.
0-4 (no score - <3/hip)
5-10 (no score-<6/hip)
