Stiff, sore achy joints, can you predict when the weather is going to change? Humans aren't the only ones who can suffer from arthritis. One out of five dogs also suffers from the condition. Arthritis is pain and inflammation and swelling in the joints and affects dogs of all sizes, breeds, and ages. My 14-year-old dog Molly can sometimes predict the weather more accurately than the weatherman.
Signs that your dog may suffer from arthritis include limping, difficulty rising, stiffness, decreased activity, reluctance to run or climb stairs, and even changes in behavior such as aggression or withdrawal.
