More than one in five dogs will be affected by arthritis. Just like humans may be affected by this disorder, dogs and cats may be affected also.
Arthritis basically means inflammation of the joints. Most of the joints in the body depend on a layer of cartilage acting as a cushion, which also provides a smooth surface so the adjoining bones can move freely over each other. This is assisted by the lubrication provided by the synovial fluid, the oily liquid in joints.
With arthritis, the cartilage weakens and the synovial fluid loses some of its lubricating properties, so that the movement of the bones becomes less smooth.
Arthritis can affect one or more joints anywhere in the body however the most common joints affected are the shoulders, elbows, knees, and hips.

Signs of Arthritis
As dogs are very hardy creatures, and they tend not to complain when they are suffering from pain. There are signs that may indicate your dog is suffering from arthritis. These may include one or more of the following:
Reluctance to walk, climb stairs, jump or play.
Limping.
Lagging behind on walks.
Difficulty rising from a rest position.
Yelping in pain when touched.
A personality change.
Licking of the affected joints.
These signs become more obvious as arthritis progresses, and the pain becomes much worse. As a result of the changes that have occurred in the affected joint/s, arthritis in dogs is not a condition that can be cured. But the pain and discomfort can be very effectively controlled and managed.
