The Safety of Feeding Eggshells to Dogs
Eggshells, contrary to popular belief, are safe for dogs to consume. However, there are a few precautions to keep in mind. It is crucial to use eggshells from a trustworthy source of farm-raised eggs. Avoid using eggshells from most grocery store eggs, as they are often treated with chemicals to enhance their appearance. Instead, opt for eggs from organic, pasture-raised chickens that are free from antibiotics and hormones. These eggs tend to be richer in nutrients and free from harmful additives.
To ensure the safety of eggshells, it is important to properly clean and prepare them. Rinse the eggshells thoroughly and remove any visible dirt or residue, such as chicken droppings. Allow the shells to dry completely before use. Some pet owners choose to bake the shells in the oven at a low temperature (around 200F) for 10-15 minutes to ensure thorough drying. This step also helps eliminate any potential bacteria.
Making Eggshells Digestible for Dogs
While dogs can consume eggshells, it is essential to make them easily digestible. Instead of feeding chunks of shell, it is recommended to grind the shells into a fine powder. This can be easily achieved using a clean coffee grinder or a mortar and pestle. The resulting powder can be stored in an airtight jar and sprinkled onto your dog’s meals as a supplement.
Grinding the eggshells into a powder not only makes them more digestible but also increases their surface area, allowing for better absorption of the beneficial nutrients.
The Nutritional Benefits of Eggshells for Dogs

Eggshells offer a range of nutritional benefits for dogs, making them a valuable addition to their diet. The primary nutrient found in eggshells is calcium carbonate, which plays a vital role in maintaining strong bones and teeth. Calcium is particularly important for growing puppies and pregnant or lactating dogs.
In addition to calcium, eggshells also contain other essential minerals such as phosphorus, potassium, sodium, zinc, manganese, iodine, selenium, copper, chloride, iron, and magnesium. These minerals contribute to various bodily functions and support overall health.
Furthermore, eggshells are a natural source of glucosamine, collagen, and chondroitin, which are compounds commonly used in joint supplements for dogs. These compounds promote joint health and mobility, making eggshells particularly beneficial for older dogs or those with arthritis.
How Much Eggshell Powder Should Dogs Consume?
Determining the appropriate amount of eggshell powder to feed your dog depends on several factors, including their size, age, and overall health. As a general guideline, it is recommended to add approximately 1 teaspoon of eggshell powder per 1,000kcal of your dog’s food. This dosage provides an adequate amount of calcium without exceeding the recommended levels.
However, it is important to note that eggshells do not contain other essential minerals found in bones or bonemeal, such as phosphorus and magnesium. Therefore, it is crucial to ensure your dog’s diet includes other sources of these minerals to maintain a balanced nutrient intake.
Addressing Concerns About Salmonella
One common concern when feeding dogs raw eggs or eggshells is the potential risk of salmonella. While it is true that raw eggs can carry salmonella bacteria, dogs have a digestive system that is generally well-equipped to handle bacteria like salmonella. However, to minimize the risk, it is advisable to bake the eggshells in the oven or boil them for 10 minutes before grinding them into powder. These methods help eliminate any potential bacteria, including salmonella.
Consulting with a Veterinarian
As with any dietary change or supplement, it is always best to consult with a veterinarian before incorporating eggshells into your dog’s diet. A veterinarian can provide personalized advice based on your dog’s specific needs, taking into account their age, breed, size, and any existing health conditions. They can guide you on the appropriate dosage and frequency of eggshell powder to ensure your dog receives the optimal benefits without any potential risks.
Eggshells: A Supplement, Not a Substitute
While eggshells offer valuable nutrients and can be a beneficial addition to your dog’s diet, it is important to remember that they should serve as a supplement rather than a substitute for a balanced and complete dog food. A high-quality commercial dog food should provide all the necessary nutrients your dog needs. Eggshells can be seen as an extra boost, especially for dogs with specific needs such as puppies, pregnant dogs, or those with joint issues. However, they should not replace the foundation of a well-rounded diet.
Moderation Is Key
As with any supplement, moderation is key. While eggshells provide valuable nutrients, excessive calcium intake can have adverse effects on your dog’s health. Too much calcium can lead to imbalances and may contribute to the development of conditions like kidney stones. It is essential to follow the recommended dosage guidelines and avoid excessive supplementation.
The Role of Eggshells in a Holistic Approach to Dog Health
In conclusion, eggshells can be a safe and beneficial addition to your dog‘s diet when properly prepared and used in moderation. They offer valuable nutrients such as calcium, glucosamine, collagen, and chondroitin, which support bone, teeth, and joint health. However, it is crucial to consult with a veterinarian to ensure the appropriate dosage and to address any specific concerns or considerations for your dog’s health.
Remember, a holistic approach to your dog’s health includes not only their diet but also regular exercise, proper grooming, and regular veterinary check-ups. By providing a balanced and well-rounded lifestyle, you can help your furry friend thrive and enjoy a happy and healthy life.
