Arthritis is progressive so the answer is that there is likely going to be more arthritis due to continual instability in the joint. We do not know how quickly arthritis will progress but the size and weight of the dog are often factors. Managing your pet’s weight is critical during this process as obesity will play a role in speeding up the progression of arthritis. Feeding a high protein low carbohydrate diet that is well supplemented with omega-three fatty acids has proven to reduce the speed of arthritis.
