There are different types of dog arthritis. As is the case in humans with arthritis, the problem is an inflammation in one or more joints. This can be caused by an inflammation either in the cartilage in the joint or a problem with the joint’s synovial fluid. In dogs, the most common forms of arthritis are osteoarthritis, infective arthritis, immune mediated arthritis and idiopathic arthritis.

Arthritis in dogs is usually first manifested as a slow and gradual limpness in the limbs. Lameness will be the result and may reach the point where the dog has a hard time walking. This will lead in most cases to the dog being less active in play, walks and even moving about the home. Stiffness is likely to be more severe in the morning or after a nap; the stiffness is often minimal in the daytime, however.
