is it safe for dogs to eat egg shells?

Yes, eggshells can be a safe and beneficial dietary supplement for dogs when properly prepared and offered in moderation. The primary benefit of eggshells is their high calcium content, with one large eggshell providing approximately 750-800 mg of elemental calcium, crucial for bone health, nerve function, and muscle contraction.

To ensure safety, eggshells must be thoroughly washed to remove any residue, then dried completely, either air-dried or baked at a low temperature (e.g., 200°F for 10-15 minutes) to sterilize them and make them brittle. Once dry, they should be ground into a fine powder using a coffee grinder or mortar and pestle. This powder eliminates sharp edges that could cause internal irritation or injury.

Introduce the powder gradually into your dog's food, starting with a small pinch. While beneficial, excessive calcium intake can be detrimental, potentially leading to hypercalcemia, particularly in growing puppies and large breed dogs, which can cause skeletal abnormalities. Always consult your veterinarian before adding any new supplement, including eggshell powder, to your dog's diet to ensure it aligns with their specific nutritional needs and to determine the appropriate dosage.
