Can Dogs Eat Eggshells? A Vet's Perspective

Dogs are known for loving food, so as pet owners, we want to be sure they are receiving all the vital nutrients they require. Many pet owners are unsure whether eggshells may be included to their furry friend's meals due to the popularity of natural and home-made pet diets. While eggs are a fantastic source of protein and other necessary elements for dogs, what about the eggshells? Can dogs eat eggshells without becoming sick? I've been asked this question several times by worried pet owners as a highly skilled veterinarian.

Can Dogs Eat Eggshells?

Yes, dogs can definitely eat eggshells. In fact, eggshells provide a valuable source of calcium, a mineral that is vital for bone development and maintenance, muscle functionality, and proper nerve transmission. Calcium also plays a crucial role in blood clotting and helps regulate the rhythm of the heart. Moreover, eggshells contain other important minerals like magnesium, phosphorus, and potassium, all of which serve various essential functions in the body.

Nevertheless, it is crucial to note that before feeding eggshells to your dog, they should always be crushed into small pieces. Eggshells can be sharp and may cause harm to your dog's digestive system if not adequately broken down. Additionally, it is important to ensure that the eggshells are thoroughly cleaned and boiled before being added to your dog's meals.
