Ingredients Equipment Method Notes

Ingredients
  

  • 6–12 eggshells (rinsed and dried)

Equipment

  • Baking sheet
  • Saucepan for boiling shells
  • Oven
  • Coffee grinder or blender for powdering
  • Storage jar glass, airtight

Method
 

  1. Rinse the eggshells thoroughly to remove any egg residue.
  2. Boil the shells for 5–10 minutes to kill bacteria. Drain and let them dry completely.
  3. Preheat oven to 300°F (150°C). Spread shells on a baking tray and bake for 10 minutes.
  4. Let the shells cool, then grind into a fine powder using a clean coffee grinder, blender, or mortar and pestle.
  5. Store the powder in an airtight glass jar in a cool, dry place.
  6. Use 1/2 teaspoon per pound of homemade food. Do not use with kibble or already fortified meals.

Notes

Only use with homemade meals that are not already calcium-balanced. Do not add to commercial kibble or canned food. Avoid use in dogs with kidney issues or calcium sensitivity. Always consult a vet when creating a long-term homemade diet.
