On Eggs

Raw egg whites will prevent the dog from absorbing biotin, a B vitamin, but not if you them with the yolks.

Egg shells have plenty of calcium. Dont throw the shells after you use the egg. Wash them well and dry them under heat(over a hot pan or in the oven) so that the mineral oil sprayed over the eggs for preserving it is gone. After you have accumulated enough dried, clean egg shells, buzz them in a blender. Make sure the eggshell powder is smooth. You dont want sharp bits hurting the dog. Grind them smooth, please!
