Yes, dogs can eat eggshells. Just like eggs, they have some surprising health benefits! Consider again the way dogs would consume eggs in the wild – they don’t remove the shell. Instead, they eat the whole egg raw, shell and all.
Eggshells are similar to bones and are full of calcium and phosphorus. Calcium and phosphorus support healthy teeth and bones and calcium gives a healthy boost to the heart, muscles, and immune system. Phosphorus also helps the body efficiently use fats and carbohydrates and assists in cellular repair.
It’s essential for the heart to function optimally as well as ensuring that the bones and teeth are strong among other things.
How to Make Eggshell Powder?
You can grind up eggshells and mix them into your dog’s food as a calcium and phosphorus supplement. Just be sure you’re using farm fresh eggs rather than bleached white grocery store eggs. The chemicals used to clean and bleach eggshells in typical store-bought eggs may remove or compromise many of the vitamins and minerals in the eggshells and even make them harmful to dogs.
You can use a blender or food processor to grind up the shells into a powder and store it in an airtight container in the refrigerator for up to two months.
Remember that this is a supplement and not a source of food on its own. Add only a little of the eggshell powder, about one teaspoon or less per day, to your dog’s food. The ground shell of one egg is about a spoonful and meets the recommended amount per day for a dog.
Are EggShells Safe?
Traditionally, dogs (and cats) in the wild would eat whole raw eggs directly from the nest without any concern of contamination or choking on shells, unless any jagged or sharp pieces catch on his throat or esophagus.
However, you won’t reap the same health benefits because dogs don’t digest unground eggshells well and they need to be in powder form for your dog to absorb all the nutrients. Otherwise, it will pass through undigested and you may find flecks of eggshell in his stool.
