Purina Pro Plan Puppy Feeding Chart

We feed our puppy (14 week old golden retriever) Purina Pro Plan High Protein Shredded Blend Chicken & Rice Formula. They have a feeding chart on the back, and a different feeding chart online, so I’m struggling to know if I’m feeding her too little, too much, etc. I’m not sure if there was a change to their food resulting in changes in measurements. She’s currently 18.4lbs and the vet says she’s a healthy weight (last appointment 7/31). Goldens have a reputation for overeating, and I want to keep her a healthy weight through puppyhood and adulthood. Her ideal weight as an adult will be between 55-65lbs.
