Can Dogs Eat Egg Shells
Can dogs eat egg shells?
Yes, dogs can eat egg shells — and in fact, they can be quite beneficial when given correctly. Egg shells are full of calcium and other natural minerals that help support healthy bones, teeth and muscles. That said, they must be properly prepared before being offered to your dog. Crunching into a raw shell straight from the egg box isn’t the best or safest way to enjoy this natural supplement, but with a little care, egg shells can be a gentle boost to your dog’s diet.
Are egg shells good for dogs?
Egg shells are rich in calcium carbonate, which plays a vital role in your dog’s bone health and overall wellbeing. They also contain trace minerals such as magnesium, phosphorus and potassium. For dogs who need an extra calcium boost — perhaps those on a home-cooked diet or older dogs with weakening bones — powdered egg shell can be a helpful addition, as long as it’s given in moderation and with guidance.
Are raw egg shells safe for dogs?
Raw egg shells are not toxic, but they do carry a small risk of salmonella and other bacteria, just like raw eggs. If you plan to feed raw egg shells, it's important to wash the shells thoroughly or source your eggs from a reliable, organic supplier. However, most dog owners find it safer to bake or boil the shells before use — it kills any bacteria and makes the shell easier to crush into a fine, digestible powder.
Can dogs eat whole egg shells?
Some dogs may try to crunch on a whole egg shell, especially if you feed them raw eggs as part of a raw diet. While it’s not necessarily harmful, the edges can be sharp, and some dogs may find the texture unpleasant or struggle to digest larger pieces. A much safer way to serve egg shells is to crush or grind them into a fine powder and sprinkle it over their food — easy, safe and just as nutritious.
How do you prepare egg shells for dogs?
To prepare egg shells safely:
- Rinse them thoroughly to remove any egg white or yolk.
- Bake them in the oven at a low temperature (around 150°C) for 10 minutes to kill any bacteria.
- Once cool, grind the shells into a fine powder using a clean coffee grinder or food processor.
This powder can then be stored in an airtight jar and used as a little sprinkle on your dog’s food — no mess, no crunching, just a simple natural supplement.
How much egg shell powder can a dog have?
As a general guide, half a teaspoon of powdered egg shell contains roughly 1,000mg of calcium. Small dogs only need a tiny pinch, while larger dogs may benefit from up to half a teaspoon — but always check with your vet, especially if your dog is already on a balanced commercial diet. Too much calcium can cause issues, so it’s best to treat it like a supplement rather than a snack.
Can puppies have egg shells?
Puppies need plenty of calcium for their growing bones, but it’s very easy to overdo it. If your puppy is on a high-quality puppy food, they’re likely getting all the calcium they need. Adding extra without advice from your vet could cause imbalances in their growth, so it’s best to hold off unless your vet recommends it.
Are eggs and egg shells good together for dogs?
Yes — eggs and shells make a naturally balanced pairing. The egg provides protein, fats and vitamins, while the shell offers minerals and calcium. If you’re feeding raw or home-prepared meals, using the whole egg (safely cleaned and prepared) can be a lovely, nutritious boost. Just make sure everything is handled hygienically and introduced slowly into your dog’s diet.
Can dogs be allergic to egg shells?
Allergies to egg shells are rare, but not impossible. If your dog shows signs of a reaction — like itching, vomiting or a change in stools — it’s best to stop and consult your vet. Always start with the tiniest amount when trying something new, and introduce it slowly alongside their usual food.
o egg shells help with arthritis or joint support?
While egg shells themselves are a lovely source of calcium, it's actually egg shell membrane — the thin, filmy layer inside the shell — that’s thought to support joint health. It contains nutrients like collagen, glucosamine and chondroitin, which may help dogs with arthritis or mobility issues. Some supplements include this membrane, but it’s tricky to collect at home — so if joint care is your goal, it’s best to speak to your vet about a dedicated joint supplement.
Can egg shells replace calcium supplements?
They can contribute to calcium intake, but only under guidance. If your dog is on a homemade or raw diet, powdered egg shells are a natural way to boost calcium. However, commercial dog food is already balanced — adding more calcium could throw things off. Always ask your vet before replacing or adding supplements, just to be safe and gentle on your pup’s system.
Are egg shells safe for senior dogs?
Yes, when prepared properly, powdered egg shells can support ageing bones and help prevent brittleness in older dogs. Just be cautious with quantities — older dogs often have slower digestion and may be on other medications, so it’s always good to go slowly and keep your vet in the loop.
Can I feed eggshells from shop-bought eggs?
Yes — but make sure you wash them thoroughly first. Organic, free-range eggs are often the best choice if you’re feeding raw, as they may carry fewer risks from bacteria. Baking the shells before grinding also adds an extra layer of safety. Never use eggshells that have gone off or are visibly damaged.
What if my dog eats an eggshell accidentally?
If your dog sneaks a bit of raw eggshell from the bin or while you’re cooking, don’t panic. Most dogs will pass it without issue, especially if it was just a small piece. Keep an eye out for any signs of tummy upset or discomfort, and give your vet a ring if you’re worried. A crunchy nibble now and then is usually harmless, but sharp or jagged shell pieces could irritate the gut in sensitive dogs.
Creative ways to use powdered egg shell for dogs
- Sprinkle on top of meals as a natural supplement
- Blend into homemade dog treats or biscuits
- Mix into a spoon of plain pumpkin or mashed veg
- Use it as a topper with a raw egg, if your dog enjoys them
Just remember: powdered shell doesn’t have a strong smell or taste, so most dogs won’t even notice it’s there — but their bones will quietly thank you.
Can you store powdered egg shell long term?
Yes — once baked and ground, you can store powdered egg shell in an airtight jar or container in a cool cupboard for up to two months. A small batch goes a long way, and it’s a lovely, sustainable way to use something that might otherwise go in the bin.
