This book Im reading Raw & Nutural Nutrition for dogs by Lew Olson PhD, she recommends to boil the eggs, leave egg shells on a tray in warm place over night, then ground up.. If ur feeding Raw Meaty Bones they are a great source of calcium, they wont need the extra calcuim if their diet is raw, But if ur dogs aren’t on a Raw diet then..half a teaspoon of grounded egg shells sprinked on meal..Im doing this at the moment grounded up the egg shells & putting in spice jar..
