Aging joints in dogs

The terms “arthritis” and “osteoarthritis” refer to a disease that affects joint cartilage. It's the most common joint disease in dogs. The term “arthrosis”, synonymous with “osteoarthrosis”, is most often used.

The first signs of arthritis are often very subtle. Dogs may refuse to do certain exercises, such as going up or down stairs, or to jump. As the disease progresses, however, periods of sustained or intense activity may be followed by lameness and stiffness. These symptoms generally disappear after a few days' rest.

As the joints deteriorate, stiffness may increase after periods of rest. Once the animal has begun to move, it seems to “warm up” and stops limping and walking stiffly. Symptoms often tend to worsen in cold, damp weather.

When arthritis is pronounced, stiffness and lameness are common, and the animal may be in constant pain. Signs of pain include shivering, panting, restlessness and non-specific signs such as decreased appetite, apathy, reluctance to move and moaning. The animal may also become irritable or reclusive, and may bite or nip when approached or touched.

Recent advances in arthritis treatment have improved the prognosis for patients suffering from this crippling disease. If you suspect your pet is suffering from arthritis, consult your veterinarian, who will diagnose the condition and suggest appropriate treatment.
