Eggshell Calcium For Your Dog

If you your dog is on a homemade diet, he/she will need added calcium. One way to get the calcium is with a calcium supplement: like eggshell calcium or including 20 percent raw meaty bones. We prefer the eggshell calcium!

As the name suggests, eggshell calcium is made from “recycled” eggshells (and eggshell membrane) that you’d otherwise discard.

  1. Wash the shells and let them dry on a cookie sheet. Place the cookie sheet in the refrigerator and let them dry overnight.
  2. Preheat oven to 200 degrees F and bake for 10-15 minutes.
  3. Eggshells should be completely dry. (If you washed the eggshells shortly before baking, allow extra baking time. Eggshells must be completely dry before grinding.
  4. Grind the eggshells in a clean coffee grinder or a blender until all large pieces are ground to a powder. If the same grinder is used for coffee, make sure it has been cleaned before using it for the eggshells.
  5. Store in a jar with a lid. We prefer keeping the jar in the fridge, but it will do just fine in your pantry in a dark place.

For a complete homemade diet, you’ll want to add about one-half teaspoon ground eggshell per pound of fresh food. If you feed both fresh food and commercial food, just add the eggshell to the fresh portion of the meal.
