Yes, dogs can eat eggshells in moderation, and they can even be beneficial for them. Eggshells are a great source of calcium, which is essential for your dog's bone health, teeth, and overall well-being. However, there are some important considerations:

1. Preparation:
Clean thoroughly: Make sure the eggshells are clean and free of any leftover egg residue. This helps avoid any risk of bacterial contamination (such as salmonella).
Crush or grind: It’s best to crush the eggshells into a fine powder before feeding them to your dog. Whole eggshells can be difficult for your dog to digest and could pose a choking hazard.
2. Moderation:
While eggshells are a good source of calcium, too much calcium can be harmful to dogs. Excess calcium can lead to health issues such as kidney problems or mineral imbalances. Always offer eggshells in small amounts, and use them as a supplement to your dog's diet, not as a primary food source.
3. Health Benefits:
Calcium: The most significant benefit of eggshells is the calcium they provide. This mineral supports bone strength, dental health, and overall growth.
4. How to Feed Eggshells to Your Dog:
Add to food: You can sprinkle a small amount of ground eggshell powder onto your dog’s regular food.
Use occasionally: Don’t give eggshells to your dog every day; instead, offer them as a supplement a few times a week, depending on your dog’s needs.
If you’re uncertain about adding eggshells to your dog’s diet or if your dog has any health conditions, it’s always best to consult with your veterinarian first.
