What are your thoughts RE Phosphorus x Calcium Levels (as phosphorous is used in Calcium absorption, right?)?
I was looking into foods for my Presa (spanish mastiff, essentially), and a good friend (some vet training, very into the raw diet) noted that while protein isn’t so much of a concern aside from the fact that too much might cause loose stools, said that the Cal/Phos Ratio is what was really important. From my lookings, it seems like 1:1.2-1.4 Cal/Phos is what people aim for in larger breeds.
Your thoughts?
