calcium depletion

Question
I would like to know what I can use to put more calcium into her diet

Answer
Low calcium is rare.  Is this something a vet diagnosed?  If so, did he suggest anything?  Too much calcium for a puppy can cause problems with using what it needs.  I certainly would never give a puppy extra calcium unless ordered bya vet and even then, I might get a second opinion.  

If you are absolutely sure she needs it, bone meal, yogurt, or calcium tablets will work.
