In dogs, even a minor injury can lead to arthritis later in life. The conditions to which some breeds of dogs are predisposed, such as hip dysplasia can also mean a predisposition to developing arthritis as the dog ages. Even dogs who have never suffered an injury in their lives may well develop arthritis as they age.

The most common dog arthritis is osteoarthritis which is a degenerative disease in the joints where the cartilage will need remodeling, and then the new bone causes the arthritis. The dog arthritis symptoms are usually a gradual onset of limpness in the limbs. In other words lameness will result to where the dog finds it difficult to walk. Most often a dog will also be less likely to be active such as walks, playing, or even going up stairs.
