Here is the guide from the Purina website to answer your question, OP:
Now that the chart is available to answer your question, I'd love to encourage you to shop around and look for other brands of kibble in your price range that might have more 'bang for your buck'. Puppy Chow may meet the most basic guidelines for nutrition, but it has a lot of filler and a number of ingredients that can cause problems.
Especially now during critical growth and development, good nutrition will really give your pup what he needs. You'll start seeing dry coat/bad coat as he ages (if you aren't already) because he'll be missing some essential fatty oils and acids that Puppy Chow does not include. You don't have to spend a ton to get decent nutrition; if you have a feed store there are quite a few brands (like Diamond Natural, Taste of the Wild, 4Health) that are still very reasonably priced and will get your pup what he needs. And with a low- or no-grain formula you'll actually feed much less... the bag lasts longer and as a bonus you'll get less poop!!
