It's harder than you think to get the calcium right. Especially if you can't (or don't want to) give your dog bones. You might not know this, but eggshells are a very incomplete source of minerals. Sure, they have lots of calcium ... but they can't balance most raw diets. The same goes for coral and seaweed calcium.
About 99% of the calcium in your dog is stored in his bones. Along with phosphorus, calcium is critical for skeletal health so it’s important for dogs to get enough in their diets. The remaining calcium is mainly found in the blood and lymphatic system where it plays a role in hormone function, cell structure, enzyme activity, cardiovascular and immune function.
There are several sources of calcium you can add to your dog’s food … but they’re not all the same and they’re not all suitable for puppies. The most common calcium supplements and foods you can add include:
SOURCES OF CALCIUM
Egg Shells: While many home made diets use egg shells as a source of calcium, they’re deficient in other minerals. The amount to feed is about 1 teaspoon per pound of food, which is about 5 grams. Here’s how calcium balances the minerals in foods for adult dogs. As you can see, egg shells can only be used with very lean meats. If you feed more than 10% fat (including any oils you add to the food), your dog will not get enough phosphorus.
Coral Calcium: Like egg shells, coral calcium is also extremely high in calcium but relatively low in phosphorus. This also makes coral calcium a poor choice for adult dogs eating a moderate to high fat diet. If you choose coral calcium as a calcium source, you need to make sure your dog’s meals are very lean or there can be a mineral imbalance and phosphorus deficiency. Feed 3/4 teaspoon per pound of food that’s no more than 10% fat. Any food that contains more than 10% fat will cause a phosphorus deficiency.
Seaweed Calcium: Seaweed calcium is another calcium source that’s high in calcium and low in phosphorus. This also makes it a bit tricky to use with anything but very lean meats. Like coral calcium, adding more seaweed calcium won’t help balance the minerals because there will still be too little phosphorus. Feed 1 teaspoon per pound of food that’s no more than 10% fat.
Bone Meal: is bone that’s been dried, either with or without heat. Minerals are pretty resistant to heat, so it’s generally safe to heat and powder bones. But you can also find higher quality sources of bone meal that hasn’t been heat treated, which would be preferred.
The benefit of bone meal over other sources of calcium is that there’s much less risk of mineral imbalance. Bone meal will almost always give you the proper ratio of calcium and phosphorus, just as real bones will. Feed about 2 teaspoons per pound of food to adult dogs.
In the end, the adage of sticking close to nature rings true. Bones, with their inherent balance of calcium, phosphorus, magnesium, and vitamin D, stand unrivalled in their suitability for canine diets. This natural option not only supports the nutritional framework for puppies but also offers a model for supplement selection that prioritizes minimal deviation from nature's blueprint.
The pursuit of optimal health for our canine friends underscores the importance of choosing supplements that align with their natural dietary needs, eschewing synthetic alternatives in favor of those that nature itself would endorse.
