Older people suffer from arthritis, a form of degenerative joint disease that is caused by cartilage destruction. Older dogs are not exempted from this malady. Signs that your pet is developing this condition will be evident when he starts to limp or favor one or more limbs.

You will notice a pronounced slowness or reluctance when rising from a resting position. Consult your vet immediately and ask if your pet might already need a dog joint supplement.
