If your dog eats homemade food, ensuring plenty of calcium in the diet is a must. A simple way to introduce more calcium is by making your eggshell supplement for dogs.
1 dozen eggshells, or more, cleaned, dried and sanitized - see note
Remember to consult your veterinarian before drastically changing your dog's diet or giving your dog new supplements.
Clean and dry about a dozen eggshells. As it may take a bit of time to accumulate enough eggshells, you can store them in an airtight container at room temperature.
Preheat the oven to 300 degrees, and spread the eggshells on a lined baking sheet. Bake for about 5 minutes.
Allow the eggshells to cool after baking, and then grind them into fine powder. No sharp edges should be left that could cut a dog's mouth or esophagus.
The supplement should last up to 2 months when stored in an airtight container at room temperature.
