Benefits and Risks of Eggshells

Eggshells are packed with calcium, which is essential for a dog's bone health. They can also provide slight amounts of other minerals. But, raw eggshells may harbor harmful bacteria like Salmonella. Too much calcium can also cause health problems, particularly for puppies or large breeds.

How Much Eggshell Can Dogs Eat?

It depends! For small dogs, a quarter of an eggshell twice a week is usually sufficient. Medium dogs can manage half an eggshell, while large dogs might handle a whole one. Always crush the eggshells into a fine powder to make them digestible. Frequency? Once or twice a week should do the trick.

Common Misconceptions

Many believe that eggshells can cause constipation or gastrointestinal blockages. That's true only if dogs consume them in large, uncrushed pieces. By crushing the eggshells into a fine powder, these risks are significantly minimized.

What If Your Dog Reacts Badly to Eggshells?

If your dog shows signs of gastrointestinal distress, like vomiting or diarrhea, after eating eggshells, stop giving them this treat. Offer plenty of water and see if their condition improves. If symptoms persist, consult your veterinarian promptly.

What are Healthy Alternatives?

Looking for other ways to boost your dog's calcium intake safely? Here are some options:

  • Plain Greek yogurt: A tasty source of calcium and probiotics.
  • Cottage cheese: Nutritious and easy to digest.
  • Bone meal powder: An excellent calcium supplement, but consult your vet for dosage.


Eggshells can be a beneficial supplement to your dog's diet, but moderation and proper preparation are key. Always observe how your dog reacts to new foods and consult with your vet, especially if you have concerns about your dog's health or specific dietary needs. After all, a happy, healthy pup is what every dog owner strives for!
