Do you
ever read about
a dog breed
and discover that
a particular breed
can be prone
to a number of diseases -
most of which you can't understand? Are you
in the process of choosing
a dog and you
want to know which breed-specific
hereditary disease that
the breeder should have screened out
in the breeding stock?
Most
breeders spend a lot of time and resources trying
to get rid of
genetic diseases in their lines. However,
some amateur breeders and
puppy mills
are breeding
dogs without screening the parents and perpetuating poor genetic health.
This
article is not exhaustive but
will attempt to describe
some common hereditary musculoskeletal
diseases and indicate some of the dog breeds that have shown a tendency to inherit these diseases
in the past. Since so many dogs have inherited
orthopedic problems, these
disorders are extremely well researched and studied. If you want to check on a particular dog breed you can go to www.dog-breed-facts.com and search on a particular breed for its health issues.
There are a number of common inherited diseases for which reputable breeders screen their breeding stock. The Orthopedic
Foundation for Animals
(OFA) has specialists evaluate
X-rays, DNA, thyroid, cardiac and other tests and register the results. A prospective pure-bred
puppy buyer should
ask to see the OFA results for the dog's sire and dam.
Chondrodysplasia
or dwarfism in the
legs is a disease that causes malformation of the carpal and radius bones of the
front legs resulting in a stunted and bowed look. Puppies born with
this disease do not show any signs until they
grow older. The disease can be painful and often the only choice
is to euthanize the dog. This disease
is most common in the Alaskan malamute and the Beagle.
Elbow
dysplasia is a hereditary disease in which the elbow joints of the front legs are malformed. Lameness usually makes its appearance around 7 to 10 months of age and is
treated by anti-inflammatories and also surgery. All breeds are susceptible to the disease but it is most common in large male breeds. These breeds
include the: Basset hound, Bernese mountain dog,
Bloodhound, Bouvier des Flandres, Chow Chow, German shepherd, Golden retriever, Great Pyrenees, Irish wolfhound, Labrador retriever, Mastiff, Rottweiler, Saint Bernard and Weimaraner.
Hip dysplasia is a disorder that results when there is a loose fit of the
'ball and socket' hip
joint and the ball may continuously slide part way out of the socket.
Over time this will cause osteoarthritis in the joint and the dog will become
lame and weak in the hind
end. Some relief can be found with the use of nutriceuticals such
as glucosamine and
chondroitin, and anti-inflammatories. Some cases are so bad that the dog must have
surgery or be euthanized. Ensuring that your dog isn't overfed and overweight can delay the onset of hip
dysplasia. Larger breeds that grow fastest
during the first four months seem to be more prone to this disease.
Hip dysplasia is the most common inherited orthopedic disease in large and giant breeds and many medium-sized breeds as well.
Legg-Calve-Perthes is a disease of the hip joint where the ball or head of the femur deteriorates and causes
pain and lameness in the hind leg. This disease usually affects young small dogs aged from
4 to 12 months. This
condition is successfully treated by surgery. This disorder can affect all terriers,
Chihuahuas, Dachshunds, Miniature pinscher, Miniature
poodles, Pugs and Toy poodles.
Panosteitis or 'pano' is a common condition which
suddenly causes lameness in a growing puppy or adolescent dog. The lameness is a result of
inflammation of the long bones of the front and hind legs and can be mild to severe. A veterinarian will probably prescribe pain medication and ask you to restrict exercise. Affected puppies usually grow out of the condition as they mature. It is most common in male medium- to giant-sized dog breeds which include the: Afghan Hound, Basset
hound, Doberman pinscher, German shepherd, Great Dane, Great Pyrenees, Labrador retriever and Rottweiler.
Luxating Patella (Patellar luxation) or slipped stifle is a hereditary condition where the knee cap slips out of its groove. In some cases, the kneecap will slip
back into place while in other cases; a veterinarian may need to put it back in place. If it is not corrected through surgery,
then osteoarthritis will usually result. The condition is quite prevalent in toy breeds. It is commonly seen in the Affenpinscher, Australian terrier, Basset hound, Boston terrier, Chihuahua, Cavalier King Charles
Spaniel, English Toy Spaniel,
Maltese, Papillon, Pekingese, Pomeranian,
Poodle (miniature and toy) and Lhasa Apso.
