If you’ve ever cracked an egg for breakfast and wondered whether that shell could benefit your dog, you’re not alone. Eggshells are almost pure calcium carbonate, which can support strong bones, teeth, and nerve function. But before you toss a shell into your pup’s bowl, there are a few critical steps to make it safe and effective. Let’s break down exactly how to turn eggshells into a healthy, homemade calcium supplement for your dog.
Why Eggshells? The Calcium Boost Your Dog Might Need
Calcium is essential for dogs, especially for growing puppies, nursing mothers, or active breeds like the Bernese Mountain Dog. A calcium deficiency can lead to weak bones, muscle tremors, and even heart issues. Eggshells provide a natural, bioavailable source of calcium without the additives found in some commercial supplements. However, most dogs eating a balanced commercial diet already get enough calcium, so adding eggshells should only be done under guidance.

How to Prepare Eggshells for Your Dog
Raw eggshells can carry salmonella, and sharp edges can hurt your dog’s mouth or digestive tract. Here’s the safe preparation method:
- Rinse thoroughly after cracking to remove any egg white residue.
- Boil the shells for 10 minutes to kill bacteria, then let them cool.
- Dry completely in a low oven (200°F) for 15-20 minutes, or air-dry overnight.
- Grind into a fine powder using a coffee grinder or mortar and pestle. A coarse powder can irritate the gut.
Store the powder in an airtight jar in a cool, dry place for up to two months. This simple process turns a kitchen scrap into a powerful supplement.
One medium eggshell yields about 800 mg of calcium, which is roughly the daily requirement for a 50-pound dog. That’s a lot of bang for your breakfast!
How Much Eggshell Powder to Give Your Dog
Dosage depends on your dog’s size and diet. A general guideline is 1/2 teaspoon of finely ground eggshell powder per 20 pounds of body weight per day, mixed into their food. For a small dog (10 pounds), start with 1/4 teaspoon. For a large dog (80 pounds), you might use 2 teaspoons. Always start with half the recommended amount and watch for any digestive upset. If your dog is on a raw or homemade diet, they may need more calcium, but if they eat a complete kibble, extra calcium can cause imbalances. Consult your vet before adding any supplement, especially if your dog has kidney issues or a history of bladder stones.
Risks and Precautions: What Every Owner Should Know
While eggshells are generally safe, there are a few risks to keep in mind. First, salmonella is a real concern with raw shells, so always boil them. Second, sharp shell fragments can cause tears in the esophagus or intestines, which is why grinding to a fine powder is non-negotiable. Third, too much calcium can lead to hypercalcemia, which causes vomiting, lethargy, and kidney damage. Finally, if your dog has a history of calcium oxalate bladder stones, avoid eggshells entirely. If you’re also introducing a new pet into your home, like a cat, you might wonder about their compatibility. For instance, Are Norwegian Forest Cats Good With Dogs?

Alternatives to Eggshells for Calcium
If eggshells aren’t your thing, there are other natural calcium sources. Plain, unsweetened yogurt, canned sardines (with bones), and bone meal powder are all good options. For dogs who need extra joint support alongside calcium, consider that large breeds like Bernese Mountain Dogs are prone to hip issues.

Always choose a calcium source that fits your dog’s specific health needs and dietary restrictions.
When to Talk to Your Vet
Before you start any new supplement, including eggshells, have a chat with your veterinarian. They can check your dog’s current calcium levels with a simple blood test and recommend a precise dosage. This is especially important for puppies, senior dogs, or those with chronic conditions. Your vet can also help you decide if eggshells are better than a commercial supplement.
