Calcium Carbonate
The primary mineral in eggshell. Supports normal bones, teeth, and muscle function when used in the right amount.
Natural Membrane
The thin membrane may contain naturally occurring collagen-type compounds that support connective tissue.
Trace Minerals
Eggshell naturally contains small amounts of minerals beyond calcium. Simple, whole-food, and single ingredient.
No Additives
No fillers, no flavoring, no oils, and no mystery ingredients. Just finely ground eggshell.
Why calcium matters in fresh food
Meat is naturally higher in phosphorus, so dogs and cats eating fresh or home-cooked food may need calcium added in the right amount. Eggshell calcium powder can help support a better calcium-to-phosphorus balance when used correctly.
- Supports strong bones and healthy teeth
- Useful for fresh-food and home-cooked diets when calcium is needed
- Single ingredient — nothing hidden, nothing added
- Finely ground so it mixes easily into food
Every pet and every diet is different. Start small, use the suggested guide as a starting point, and follow your veterinarian’s guidance for your specific pet.
Suggested serving guide
Mix into your pet’s food once daily. Start with a smaller amount and increase gradually over a few days to let your pet adjust.
| Pet Weight | Suggested Daily Amount |
|---|---|
| Under 10 lbs | ⅛ teaspoon |
| 10 – 25 lbs | ¼ teaspoon |
| 25 – 50 lbs | ½ teaspoon |
| 50 – 80 lbs | ¾ teaspoon |
| 80 lbs and over | 1 teaspoon |
Mix into wet food, a Woof Wagon meal, or a home-cooked dish. Too much calcium can be a problem too, especially for puppies, kittens, seniors, or pets with kidney or urinary concerns.
Also great for plants 🌱
Eggshell powder is a natural calcium source gardeners have used for generations. It is simple, chemical-free, and easy to work into soil.
Support Roots
Mix into soil for a slow-release calcium boost that supports root and cell-wall development.
Tomatoes & Peppers
Calcium is important for plants that can struggle with blossom-end rot when calcium uptake is poor.
Gentle Soil Support
Works gradually over time. Useful for edible gardens, herbs, roses, and houseplants.
Use with common sense
Eggshell calcium powder is a supplement — not a complete meal replacement. We recommend consulting your veterinarian before adding any supplement to your pet’s routine, especially if your pet is:
- A puppy or kitten still growing
- Pregnant or nursing
- A senior pet with changing nutritional needs
- Managing kidney disease or urinary concerns
- On a veterinarian-prescribed restricted diet
The right amount depends on your pet, the food being fed, and the rest of the diet.
