First, go here and read /forums/topic/large-and-giant-breed-puppy-nutrition/
There is a google doc in there that Hound Dog Mom posted. She did a ton of research of which foods actually have the appropriate amount of calcium for large breeds. A lot of the so called large breed foods really are not ok for large breed puppies. They were formulated from old bad research that has since been disproven. Pick a few foods from her list and rotate through them, it’s ok to give your other dog the same food. Rotating foods is healthier for your dog, just like people should eat a variety of foods for optimal health, dogs should too.
