When I am trying to decide what brands to feed my large breeds I always contact the company and ask them the MAX calcium & phosphorus is on a dry matter basis.
Companies are required to label the min. That’s not helpful when you have to know the upper limit of certain nutrients.
Even if I have fed that food before. If it’s been a while I contact them again to find out about any changes.
Many foods say they are formulated for large breeds yet have calcium amounts at or beyond the max. You must find out the exact percentage.
