Eggshell Powder 101: Why I Make It for My Dog
If you see me saving eggshells like a little squirrel, mind your business...I’m just making my dog a nutrient-packed, zero-waste calcium supplement. 😌🐾
Here’s why I swear by homemade eggshell powder and how you can make it, too.

🥚 Why Eggshell Powder Is a Total Win for Dogs
Eggshells are basically tiny calcium powerhouses, about 95% calcium carbonate, which is exactly why they’re so great for bone strength, muscles, and nerve health. Instead of buying a supplement, you can literally make one from breakfast.
What I love most:
• It’s affordable (free!)
• It’s highly bioavailable, dogs absorb eggshell calcium really well
• It reduces food waste, aka, dog health and sustainability high-fiving each other
Studies even show eggshell calcium performs as well as (or better than!) store-bought purified calcium carbonate. So yes, your kitchen scraps can hang with the big dogs.

🦴 How Eggshell Calcium Supports Your Pup
Dogs need calcium for:
• Strong bones & teeth
• Muscle movement
• Heart and nerve function
• Growing puppies or nursing mamas especially
• Active dogs or seniors who need extra support
1 tsp of eggshell powder = ~1,800–2,000 mg calcium
That’s plenty to meet most adult dogs’ daily needs when added to a balanced meal.

🌱 And the Membrane? That’s Joint Gold.
That thin, papery membrane inside the shell? Don’t toss it.
It naturally contains:
• Glucosamine
• Chondroitin
• Collagen
• Hyaluronic acid
Basically, everything people buy expensive joint supplements for.
It can help reduce stiffness, support cartilage, and keep joints cushioned, especially great for seniors or breeds with hip/joint issues.

🔥 How To Make Eggshell Powder Safely
STEP 1: Collect & Rinse
Rinse the shells to remove egg white residue.
STEP 2: Boil for 5 mins & then Bake at 200°F for 10–15 minutes to dry and sanitize them.
STEP 3: Grind
Once cool, grind into a fine, smooth powder (coffee grinder = perfection).
The finer, the better, no sharp edges, easier digestion.
Bonus: Peel off the membrane before baking if you want to add that joint-supporting goodness separately.

🥚 What Kind of Eggs Should You Use?
Aim for organic, pasture-raised eggs for cleaner, safer shells and better nutrient density. Your dog deserves the good stuff.
⸻
💛 A Few Feeding Guidelines
• Adult dogs: ~1 teaspoon per 1,000 calories
• Puppies/pregnant/nursing dogs: ~1.5 teaspoons per 1,000 calories
• Introduce gradually
• Mix into meals for best absorption
Eggshells are a calcium booster, but not a full mineral replacement, pair with phosphorus-rich foods (like meat) and magnesium sources (like leafy greens) to keep things balanced.

🍳 And Yes… Dogs Can Eat Eggs Too
Raw or cooked.
Raw keeps the full nutrient profile.
Cooked is great for pups with sensitive tummies.
Just skip salt, butter, or seasonings.

Why I save all of my eggshells!
Eggshell powder is an excellent homemade supplement that taps into a natural, sustainable source of calcium for dogs. Calcium is vital for dogs’ bone density, muscle function, nerve signaling, and overall vitality. Using eggshells from your kitchen not only reduces waste but offers a bioavailable form of calcium carbonate well absorbed by dogs compared to some commercial supplements. Beyond calcium, the thin membrane found inside eggshells contains glucosamine, chondroitin, collagen, and hyaluronic acid—nutrients commonly sought after in joint supplements. This natural membrane can help support cartilage health, reduce joint stiffness, and cushion older dogs or breeds predisposed to joint issues such as hip dysplasia. Retaining and utilizing this membrane when making eggshell powder can add an invaluable joint benefit. Safety is crucial when preparing eggshell powder. Proper rinsing followed by boiling and baking at 200°F helps sanitize the shells while preserving nutrients. Grinding the shells into a fine powder prevents sharp edges, making it easy for dogs to digest and absorb. Using organic, pasture-raised eggs ensures cleaner shells with less pesticide residue, optimizing nutrient quality for your pet. When feeding eggshell powder, portion it according to your dog’s caloric intake—about 1 teaspoon per 1000 calories for adult dogs and slightly more for puppies, pregnant, or nursing females. Always introduce gradually and incorporate the powder into balanced meals that include phosphorus-rich proteins and magnesium from greens to maintain mineral balance. Additionally, dogs can safely consume eggs themselves. Raw eggs retain the full nutrient profile, which benefits dogs without sensitive digestion. Cooked eggs are gentle for sensitive stomachs, but avoid seasonings. Adding raw egg or homemade eggshell powder to your dog's diet can naturally enhance nutrition while promoting sustainability. Using eggshell powder as a calcium source is economical and effective, transforming kitchen scraps into nutrient-dense supplements. It blends holistic dog care, environmental mindfulness, and health support seamlessly for your furry friend’s long-term wellbeing.
