DIY Eat – Eggshell Powder
One of the most important supplements you’ll need to add to your dog’
meal is calcium. If dogs had the ability to chew on a good bone every
day, they would be scraping off bits of bone that then would be broken
down in the their body and used to strengthen their own bones and
teeth. It’s the job of the parathyroid to regulate the amount of
calcium and phosphorus in the blood. If a diet is deficient in
calcium, the parathyroid will go looking for it in your dog’s bones.
When the parathyroid starts secreting extra hormones in order to
balance the calcium-to-phosphorus ratio, it creates a condition known
as secondary hyperparathyroidism. This disorder can cause permanent
damage to the skeletal system, arthritis, and even broken bones. Extra
calcium will be excreted in the urine, but while it’s in the body,
excess calcium inhibits the absorption of phosphorus. So don’t overdo
a good thing.
By diverting eggshells from the compost bin you have an inexpensive
and easy solution to providing your dog the appropriate amount of
calcium. It requires only a couple of teaspoons of Eggshell Powder to
balance out the phosphorus in most diets and this recipe will make
about 12 teaspoons, each with about 1800 milligrams of calcium.

have a light tint, which is okay. Baking eggshells any longer can
produce an unpleasant smell.

grinder for 1 minute, or until you achieve a very fine powder with no
