Eggshells

Once a week every Monday our pods have one day without eating meat. That day our girls get eggs yolks. I am a supporter of the natural, separate diet, so even with dogs meal I don't mix anything. This kind of meal gives us the opportunity to give our body full of vitamins and minerals. I give eggs yolks  completely separately, as a dish for supper. I put eggs into a boiling water for one minute, next I put them to cold water. I spill egg white to bowl and I leave it for us. Our lovely pods get yummy eggs yolks high in vitamins. I leave also eggshells to dry. I put them into a glass and cover some gauze (to close access for insects). You can also put these eggshells into a paper bag. After a few days (3-4) dry eggshells are ready to mill. I use stone mortar but if you want to make it faster you can use coffee grinder. It's good to use eggshells every day, with a meal. Our pods get one teaspoon of eggshells every day (not in days when they have bones with meat).

We must remember and be careful to not give our dogs calcium and vegetables rich in oxalates together in one meal. Best serving calcium just with meat and vegetables as a separate meal. Vegetables rich in oxalate: sorrel, chard, beet, celery and parsley.

Eggshells, in particular, are a great source of calcium for dogs and cats.  Calcium, as you know, is needed for normal growth, strong bones, teeth, and claws, as well as for optimum muscle contraction.
Normally, using raw meaty bones as a calcium source is the most common and natural way to provide this vital nutrient to your dog or cat.  Raw bones can usually be fed whole; though for those pets that have damaged, fragile teeth (or no teeth at all) or for people who are not comfortable feeding whole bones to their pet, there is the option to grind up the raw bones before feeding them to your raw fed dog.  Unfortunately, most pet owners will quickly find that it is very difficult to get a hold of the equipment needed to grind hard bones, like beef, pork, or lamb.  In these cases, pet owners making their own homemade dog food often resort to using Bone Meal to supply calcium to their dog or cat.  I personally DON’T recommend using bone meal, as it is an inferior ingredient derived from the animal rendering process.

Eggshells however, present a healthy, balanced calcium source, mainly due to some trace amounts of other minerals contained in the shells.  There is a combination of 27 different mineral micro-elements in eggshell and, interestingly enough, the composition of eggshell is very similar to those found in bones and teeth.

The advantages of using eggshells as a calcium supplement for dogs include:

1. Eggshells provide one of Nature’s best natural sources of calcium
2. Powdered eggshells are easy to digest and are adequately absorbed by the digestive system
3. Using powdered eggshells in combination with magnesium and vitamin D3 (like cod liver oil) improves bone mineral density.

A great way to powder the shells is to use a coffee grinder.  This works much better than a food processor or blender.  Using a variety of eggshells sourced from chickens, ducks, or geese is also very beneficial for your pet.

One thing to consider, when supplementing your dog or cat’s diet with calcium, is to ensure that the calcium and phosphorus levels in your pet’s diet are correct.  The calcium/phosphorus balance is extremely important!  Each nutrient must be in perfect balanced in order to prevent skeletal issues in your pet.  A ratio of 1.5 parts calcium to 1 part phosphorus is appropriate for most dogs.
