One of the saddest parts about being a dog owner is watching them suffer from arthritis. Whether the result of a medical condition (like hip dysplasia) that makes them prone to arthritis, the breed, an old injury, or just old age, arthritis can strike a dog at any age. If you notice your dog walking stiffly, having trouble getting up from a sitting or lying down position, or hesitance jumping on the bed, there’s a good chance your dog is suffering from arthritis.
