Medical Problems in the Alaskan
Malamute
|
Hip
Dysplasia |
Affects
bone in the hip ball and socket. The mode of inheritance
is polygenic (controlled by a number of genes) and can
skip several generations without showing up.
Environmental factors also influence the soundness of the
hip joint.
Controlled breeding programs offer the only
means by which the incidence can be reduced. Only dogs
with good hips as determined by hip x-ray should be bred
from, however, pups from x-ray cleared parents can still
be affected, although the likelihood is reduced. Relief
can be provided to affected dogs by medication or
surgery.
Prospective buyers should make certain both
parents of the pup have been x-rayed and passed for hip
dysplasia before choosing a pup.
The Hip Dysplasia
Program and certification form can be downloaded from the
Documents & Forms page of this website,
or can be obtained from the Secretary or Health Officer. |

Chondrodysplasia
(Dwarfism) |
Affects
bone development and growth. The mode of inheritance is
simple autosomal recessive, meaning that both parents of
an affected animal must carry the gene, but may not be
affected. The symptoms are shortened, deformed front legs
with a downhill posture. Diagnosis by radiographic
examination is fairly reliable before the age of three
months.
Pedigrees can be submitted to the AMCVs Chondrodysplasia
Certification Program for analysis and determination of
the probability of that dog carrying the gene for
Chondrodysplasia - the Ch'd Applicaton Form can be downloaded from the
Documents & Forms page of this website,
or can be obtained from the Secretary or Health Officer. |

Day
Blindness |
Also
known as Cone Degeneration. Vision in bright light is
affected. Mode of inheritance is simple autosomal
recessive, meaning that both parents of an affected
animal must carry the gene, but may not be affected.
Affected pups may appear clumsy in bright light,
stumbling over obstacles, feeling their way with their
nose and paws and are unable to catch an object thrown to
them. These symptoms disappear in dim light.
Suspected
cases should be checked by a veterinarian and can be
confirmed by Electroretinograph (ERG). Affected dogs
which have learnt their way around their home can lead a
restricted but happy life - they must be kept on lead in
strange environments. |

Hypothyroidism |
A
hormonal disorder arising from deficient production of
metabolic hormones by the Thyroid Gland. The most common
sign is lethargy, but symptoms may also include dry,
coarse and sparse coat and obesity. Diagnosis is made by
a blood test. Successful treatment of this condition
requires an adequate level of hormone to be given each
day to compensate for the deficiency in secretion.
The AMCV is
attempting to monitor this problem by asking for thyroid results from
any Alaskan Malamute to be submitted to the AMCV Thyroid Register.
The Thyroid results submission form can be downloaded from the
Documents & Forms page of this website,
or can be obtained from the Secretary or Health Officer. |

Epilepsy |
A
functional disorder of the brain characterised by
symptoms related to the nervous system including
convulsions, hysteria and unusual behaviour patterns.
Epilepsy can be due to parasites, exposure to toxic
chemicals or hereditary factors.
The clinical signs may
include the dog convulsing, with or without loss of
consciousness, and may be followed by drowsiness and
disorientation for several minutes after the attack. Dogs
which have suffered an attack will appear very tired
afterward and will need to be rested. Medication can be
dispensed during stressful times to help prevent an
attack. Dogs with a history of epilepsy should not be
bred, and owners of related animals should be notified. |
|
Gastric
Torsion & Dilatation
(Bloat) |
This
condition can occur in any breed of dog at any age, but
is more prevalent amongst large, deep chested breeds such
as the Alaskan Malamute. Bloat results from the
dogs inability to pass food through the stomach
into the lower intestines and, in cases of torsion
(twisting) of the stomach, inability to vomit.
The
symptoms appear shortly after the dog has eaten and may
include distension of the abdomen, restlessness,
excessive salivation, unproductive attempts to vomit and
reluctance to move or lie down. The situation worsens
rapidly with the dog going into shock, indicated by pale
mucous membranes, rapid heartbeat and weak pulse. Death
is rapid and painful. Suspected cases must be taken
immediately to a veterinarian for urgent treatment.
Studies have indicated that overeating, swallowing large
amounts of air whilst eating (gulping) and exercising
shortly before or after eating may predispose a dog to
this condition. |
