Osteoarthritis is a chronic phenomenon characterized by the gradual destruction
(at varying speeds) of the cartilage in the joint accompanied by the development
of osteophytes (small newly formed pieces of bone). Osteoarthritis occurs when a
joint is unstable or when it is subject to trauma.
The main symptoms: to
describe this condition we use the term osteoarthritic "crises". The pain in
fact occurs in phases, being marked when the joint is cold and then diminishing
during the course of the exercise. On the other hand it is aggravated if
physical exercise is too intense. Gradually the crises occurs at closer
intervals and the intensity is greater because the osteoarthritis is developing
into blocking of the joint.
What should
be done: it is essential to avoid the onset of ankylosis; this means that
the dog must get daily, but moderate, exercise. Furthermore it is
necessary to ensure good management of the animal's weight; in fact every
additional kilogram in weight puts additional strain on joints. The vet may
advise the use of analgesic and anti-inflammatory drugs in order to limit pain,
or even "chondroprotective" drugs (chondroitin sulphate, glycosamine). In some
cases surgery may even be necessary. Specially designed food, available from the
vet, may be used in conjunction with treatment and will contribute significantly
to improving the clinical health of the dog.
