Canine Rheumatoid Arthritis: Symptoms And Diagnosis

Canine rheumatoid arthritis is an inflammatory, non-infectious erosive polyarthritis that is mediated by the dog's own immune system.  It tends to be a chronic disorder characterized by pain and swelling often caused by a deformity in the affected joint.  It's not common among dogs and if it does occur, it has no gender predilection.

Canine rheumatoid arthritis usually appears in dogs that are 2 to 6 years old, although it has been known to occur in dogs as young as 8 months and as old as 7 years.  The most susceptible dog breeds to canine rheumatoid arthritis are toys and smaller dogs.

How does canine rheumatoid arthritis develop?

It is not known what causes the condition specifically although there are speculations that a dog's immune response to the canine distemper virus may contribute to the development of the disease.  It is also thought that certain activities in the dog's body incite the production of antigens that stimulate immune responses, which ultimately lead to the deposition of immune complexes in the joints.

What are the Symptoms of Canine Rheumatoid Arthritis?

Dogs with rheumatoid arthritis exhibit symptoms of the disease often when it has already progressed.  A dog may show limping or difficulty in moving and rising.  He may also avoid normal activities such as running, jumping, playing or climbing the stairs.  Affected joint areas may also be swollen or hot to the touch.  Since dogs find it difficult to move, they usually lose appetite and may begin to lose weight.  Some dogs may even exhibit persistently high temperatures.

What Happens during Diagnosis?

A physical checkup is necessary in order for a proper diagnosis of canine rheumatoid arthritis.  An examination of your dog's medical records will help a veterinarian determine if his arthritis is the result of past injuries.  An x-ray may also be used to check your dog's bones and joints.  Once canine rheumatoid arthritis is confirmed, a treatment plan will be prescribed that will fit your dog's specific condition.

Sometimes, when the condition has already progressed, surgery may be recommended.  If you want to confirm or would prefer an alternative solution, don’t be afraid to ask.  If you prefer, you might even see another veterinarian for a second opinion...
