What you need to focus on in a large breed puppy is the calcium/phosphorus levels. If those are not in balance they can get growth abnormalities in their joints.

For growth in large breed puppies, a dog food must (on a dry matter basis) contain:

1.2 to 1.8% calcium
1.0 to 1.6% phosphorus
Calcium-to-phosphorus ratio between 1:1 and 1.8:1

The protein and fat percent are not that important. My recommendation is to feed a commercial diet that abides by AAFCO standards (this will be on the label) and just make sure it is for large breed puppies.

Don’t use nutritional supplements when feeding your large breed puppy any commercial diet as you will surely upset the balance of minerals.

I was assuming you were talking about feeding large breed puppies. If you want information on feeding an adult large breed please ask your question again and be more specific.

I hope this helps. Best wishes!
