calcium % and phos % for pup

[Dexter]

hihi ! i dont remember what is the right % of calcium and phos for puppie.

i found fromm to be 1.2% calcium and 1% phos wich seems to be good.
but i found out Innova large puppie breed have 0.9 % cal and .75 % phos !

lower is better ? or fromm is better ? what is the right % !

I have yet to find a definitive statement of what the correct percentage of calcium is, but the cal/phos ratio is crucial and should be around 1.2%:1% for calhos. In both examples you give--Fromm and Innova--the ratio of calcium to phosphorus is the same-- 1.2:1.

I look to find a food that is between 1% and 2% calcium. Many of the better quality grain-free foods have higher calcium content--1.8% is not unusual. For a young puppy, you definitely want to stay lower than 2%; some people like to stay even closer to 1% calcium.
