You need to make sure that the numbers for calcium and phosphorus you use are from a nutrient or typical analysis. Most companies do not post that on their website and some haven’t a clue what that is even when you contact them.
Ingredients don’t tell you much about a food. They are the vessels for the nutrients your dog needs and even the best looking ingredients can be a poor source of those nutrients. Instead focus on the company. Ask questions like, do they do their own independent research? Do they do AAFCO feeding trials? Who’s making the food? A co-packer or do they have their own facility? Who formulates their diets? Some guy with a marketing degree? Or several people with Ph.Ds in nutrition. It’s easy to make a food that looks good on paper, but that food can be a poor source of nutrition when made by someone who only cares about marketing a trendy food.
