Degenerative joint disease also known as arthritis, is inflammation of the joints which is caused by the wearing down of the cartilage causing bone to rub on bone.
Sometimes its caused by high usage, like working dogs and greyhounds. Sometimes its caused by a genetic disease like hip dysplasia. It can also be caused by being over weight, which in turn makes it harder on the joints.
Arthritis signs include stiffness rising or slow to lay down, unwilling to jump in or out of the car or stairs, decreased activity or excersise reluctance or dragging back legs.
