I would go by your pets behavior. My dog could not stand up without help, could not go up an down stairs, was unsteady when walking, So I started him on level 3. He's now running and jumping around. Since he was so bad, I'm keeping him on the maintenance dose of level 3. If your pet continues to display good joint health, I wouldn't change the product. If he starts to show signs of getting worse, That is when I would change to the next level.
