Which brand is the best food to give large breed puppies for the price & nutrition (Great Danes)?

Any good quality grain free food, fed properly.

Low protein and low calcium. Natural Balance original food is pretty good. It's 1.2% calcium (you don't want to go over that number) and 23% protein. It's also one of the less expensive premium foods.

Edit: Sorry, the complete name of the food is "Original Ultra® Whole Body Health® Chicken, Chicken Meal, Duck Meal Dry Dog Formula"


The Potato and Duck product is also great. 21% protein and 1.0% calcium.
