Hi Debbie-

This is the tool that we all use to calculate ca/phos ratios and ca/calorie ratios

/best-dog-foods/best-large-breed-puppy-food/

When I use the numbers you gave me for Nutro Natural Choice LID Lamb and Rice this is what the calculator tells me

Calculate
Calcium = 4.0 g per 1000 kcal
Ca to P ratio = 1.2 to 1

Safe, but…approaching the safe upper limit of 4.5g/1000 kcals for the ca/calorie ratio

You do not have to feed her for a working dog since she is not and that would cause her to lose too much weight, but you always want to make sure she does not get overweight.
