DISEASES AFFECTING THE WELSH
SPRINGER SPANIEL
FACT
SHEET 1 – HIP DYSPLASIA
WHAT IS HIP DYSPLASIA?
Hip
Dysplasia (HD) is a malformation of the hip joint (‘dys:
meaning bad and ‘plasia’ form)
The
hip joint is a ball and socket joint, the ball being the femoral head, and the
socket the acetabulum.
WHAT SIGNS SHOULD I LOOK FOR?
The
symptoms may include: sitting awkwardly, with the weight of the body being
taken by the forequarters, a reluctance to rise from the sitting position,
floppiness in the hind legs when moving, moving with a sawing gait or
‘bunny-hopping’ when trotting, resting during a normal distance walk.
Sometimes
at a walking pace, a dog will show a marked sway and the pelvis appears to rise
and fall with each step.
WHAT IS THE
HD is
usually observed between four and six months of age when the rate of
development of the puppy is at its most rapid.
It progresses significantly between then and eighteen months of age,
with most of the changes developing before two years old. In adult dogs, the changes that began in
early life may result in hip arthritis in middle or
old age. The dog may then become lame
even though no signs were noticed when it was a puppy.
WHAT CAUSES HIP DYSPLASIA?
Genetic
and environmental factors influence the development of Hip Dysplasia and affect
the final degree of lameness and disability:
The genetic mode of inheritance of HD is polygenic (multi-gene)
The
environmental factors of most importance are:
Ø 1. Feeding a correct diet that allows the puppy to grow at
a steady pace. The puppy or dog should
not be allowed to get fat. If a puppy is
excessively heavy at a young age, it can lead to overloading of the soft
cartilage of the developing joint and resulting deformation.
Ø 2. Over exercise of dogs with unstable joints will
exacerbate any wear and tear of the hips.
Exercise should be restricted in young dogs, particularly those with hip
problems.
Ø 3. Floor surfaces should not be slippery, and puppies
should not be allowed to climb stairs or steps.
IS THERE ANY TREATMENT?
There
are many courses of action that your Veterinary Surgeon may take. Almost certainly, he or she will take an
X-Ray of the hips to ascertain the degree of dysplasia in each hip (It may not
be equal)
Rest
and anti-inflammatory drugs will often help dogs showing pain after
exercise. He or she may prescribe pain
killing drugs, and if necessary others to help if arthritis proves a problem in
later life. In very severe cases, the
Veterinary Surgeon may consider amputation of the femoral head and/or a total
hip replacement.
WHAT IF I SUSPECT MY DOG HAS
HIP DYSPLASIA?
Contact
your Veterinary Surgeon and the breeder of your puppy for advice and support.
Dogs with
clinical HD should not be bred from
HOW DO I ENSURE THE PUPPY I
BUY DOES NOT HAVE HIP DYSPLASIA?
You
cannot. Hip Dysplasia is a most complex
subject. You can help by selecting from
animals that have good hips and by ensuring the environmental factors above are
adhered to. It is advisable for you to
acquaint yourself with the status of hips within the breed, and to consider
purchasing from a breeder who can supply details of the dogs in their kennel.
WHAT ABOUT ROUTINE HIP
X-RAYING?
Under
Kennel Club/British Veterinary Association Scheme, dogs over one year old may
be X-Rayed and scored. Each hip is
scored under nine predetermined criteria.
An excellent pair of hips would score 0-0, and the worst possible score
is 53-53 (total 106). The Welsh Springer Spaniel breed has a mean average score of 18. The score demonstrates the clinical status of
the hips, but does not absolutely reflect the potential for transmission of HD
of an individual dog. However, by careful selection breeders should aim to
improve or at least maintain good hip status.

BREEDING
GUIDELINES
In order to improve the hip status of the breed and
reduce the risk of breeding animals with HD, it is advised that breeders ideally
use animals that have scores below the breed average. However, hips are only one part of the dog
and improving the hip status should not be at the expense of temperament, type,
soundness or other
health issues.
