Hi Shawshank S,

I’d agree with Crazy4cats.
I home cook part of my dog’s diet and I use the balanceit supplement.

I calculated out the following for you. Making some assumptions.

NRC recommends .13 grams calcium /body weight in kg to the .75 power If your Golden weighs 70 lbs that calculates out to about 1740 mg calcium/day.

Your major calcium containing ingredients are
200 mls yogurt provide about 350 mg calcium
2 cups cooked spinach about 500 mg calcium

So using my assumptions you are providing about 1/2 of the NRC recommended daily amount of calcium and close to the NRC min amount of calcium, which my understanding assumes a high level of absorption, something that may not be achieved using spinach. Spinach is high in oxalates, which binds calcium. Cooking spinach does decrease oxalate, but personally I wouldn’t feel comfortable relying on spinach to meet my dog’s calcium needs because of variable calcium absorption and the high oxalate content.

Looking at Vit D, NRC recommended amount for a 70 lb dog is ~240 IU/day, your major source is egg yolk. 2 yolks are~ 80 IU If you use vit D fortified yogurt that may be making up the difference depending on level of fortification.

I think you need a nutritionist to evaluate this diet for you.
