I am going to teach you the correct way to make eggshell powder for your dog.

I have been using this great recipe for over 9 years and it has worked for my dog hands down.

It can work for your dog too, so stick around to learn the whole process.

  • Most advantageous of all, it is very easy to make.
  • In just 3 steps, you’ll have your ground eggshell powder recipe.

  • For your dog to enjoy a healthy diet.

But first, I’ll explain what eggshell is and what are its benefits for your dog’s health.

What is Eggshell Powder?

Eggshell powder is simply eggshells ground into a fine powder.

And it’s a great way to give your dog a source of natural calcium to help improve muscle, bone and enzyme health.

Eggshell powder also contains magnesium, iron, sodium and potassium.

Which will help protect its long-term health and prevent osteoporosis, a disease that lowers bone strength.

What are the Benefits of Eggshells for Dogs?

Eggs contain nutrients that benefit your dog, but this natural eggshell powder recipe stands out mainly for the following reasons:

High Calcium Content

Eggshell is an essential and nutritious source to keep canine bones and teeth in excellent condition.

It also helps mothers of puppies that are in the process of gestation and lactation and contributes to strengthening the growth of puppies.

Although eggshell contains important properties and minerals that will keep your dog strong,

it is necessary to introduce vitamins such as phosphorus and magnesium in its diet to compensate for its nutrition.

Bones and Teeth

Surely, at some point in our lives, we heard our parents talk to us

about the importance of drinking milk, so that our teeth and bones would grow strong.

Calcium is very important for your dog and cannot be missing at any point, since it is responsible for reducing the risk of bone diseases.

A diet rich in calcium strengthens and develops your dog’s bones in a better way, to also reduce the significant loss of bone density.

Other Benefits

The natural properties provided by eggshell powder are unmatched by

store-bought calcium supplements, as eggshell powder has the following advantages:

  • It is affordable

  • It has bioavailability

  • It reduces food waste and helps the environment

Considering the costs of supplements, it would be safe to

say that eggshell powder will not cost you anything.

If you ingest eggs, recycle the shells, wasting them will only prevent you from knowing the

great contributions this powder can bring to your dog.

Should I Use Eggshell Powder for my dogs?

It’s a complicated question to answer virtually, but considering the health benefits it will bring to your doggy friend, the answer is a resounding yes.

Is My Dog Getting Enough Calcium in his/her Diet?

Commercial dog foods already contain all the sufficient components your dog needs for a healthy diet.

However, if you prepare your dog’s food at home, the task of feeding it can be a bit more complicated.

Therefore, it is of utmost importance to follow a proper and beneficial nutritional plan to ensure that your pet’s needs are met.

1 KG 4 KG
50 mg calcium 200 mg calcium

 

The recommended calcium intake for adult dogs is 50 mg per kilogram of body weight.

In other words, a 4 kg dog will need approximately 225 mg of calcium per day.

Age, breed, sex and lifestyle play an important role in administering the proper amount your dog needs.

For example, if a female dog has been pregnant and lactating, she will need a very high source of calcium to maintain her strength and support healthy growth of her puppies.

Lack of calcium during this period of gestation can be a serious problem that can have long-term consequences, such as suffering from a disease called eclampsia. A fatal disease.

So how can you be sure if your pet needs a calcium supplement?

No Bone or Bone Replacement = Yes

In a raw food diet, calcium comes primarily from those edible bones,

if you choose not to feed your dog raw meat bones,

you will need a calcium supplement.

Powdered eggshell is excellent for your dog’s calcium needs.

Remember that eggshell is not a direct substitute for edible bone.

Powdered bone meal may be a better choice to substitute for bone.

But eggshell powder will help you adjust the calcium more precisely in your pet’s diet.

Correct Amount of Bone (or too much bone) = No

Most homemade raw dog food diets include bones,

and thus do not require additional calcium supplementation.

Therefore, if the calcium intake in your dog’s diet is within acceptable ranges,

it is not necessary to include any extra calcium supplement,

so you can skip the step of adding the eggshell powder.

Feed Commercially Prepared Raw Dog Food = No

Although powdered eggshell is an excellent supplement to homemade raw diets,

it is not necessary to add it to commercially prepared raw dog foods,

as these contain the necessary and balanced properties for your dog, i.e., they cover 100% of its needs.

Similarly, eggshell powder is also not necessary in those commercial raw diets that are not as complete as they contain ground bone.

How to Make Eggshell Powder for Dogs?

It is a very simple recipe to complete and is achieved in just 3 steps:
  • Step 1: Collect the eggshells and store them

  • Step 2: Boil for 5 minutes
  • Step 3: Grind it to a fine powder.

Step 1: Collect Eggshells

When you eat eggs at home, store eggshells for reuse.

Be sure to clean the eggshells with hot water before storing them in a bowl.

This prevents the inner membrane from spoiling and will make it easier to prepare.

Step 2: Cooked eggshells for dogs

Place the eggshells in boiling water for 5 minutes to kill harmful bacteria.

Then remove it and allow it to air dry.

Tip: If you want to prevent the egg smell from permeating the inside of your house while they are drying,

put them somewhere outside to dry, preferably in the sun.

There is also the option of baking the eggshells.

Simply preheat the oven to 300F.

Spread the eggshells evenly on a sheet pan and let them bake for 5 to 7 minutes.

Then, remove them from the oven.

Do not let them bake for more minutes than recommended as this can produce a bad odor.

Step 3: Grind it into a Fine Powder

Once dry, grind the eggshells to a fine powder.

To do this, you can use a blender, a coffee grinder, a spice grinder or a traditional mortar and pestle.

Be sure to obtain a fine powder without sharp edges that could hurt your dog when ingested.

Is Eggshell Powder Good for Dogs?

In this section, we will offer explanations so that you can feel safe and

confident about feeding eggshells to your dogs and explain the many types of benefits they offer.

In addition, we will do a brief check on the safety of eggs for canines in general.

Can Dogs Eat Eggshells Safely?

Eggshells are safe for dogs, as long as they come from a reliable farm egg source.

Avoid using supermarket eggs, as these have often undergone chemical-intensive processes

to give them their characteristic shine.

You will also need to opt for pasture-raised, organic, antibiotic- and hormone-free eggs.

These eggs are usually richer in nutrients and contain no harmful substances.

Do you Have to Grind Eggshells for Dogs?

In order for your pet to digest eggshells better, you should grind them into a fine powder

instead of just giving them to your pet in small pieces that may cause harm.

You can store the powder in an airtight jar and sprinkle it on your dog’s food to adequately provide its benefits.

Can Eggshells Really Give Your Dog Salmonella?

According to popular belief, raw eggs can pose a high risk of salmonellosis for dogs.

But the reality is that dogs have a highly developed digestive and immune system,

so they are able to fight off the salmonella bacteria found in raw eggs.

For safety though, always ensure the shells have been boiled first.

You can bake the shells for a few minutes and let them dry before crushing them completely.

Can Dogs with Kidney Disease Have Eggshell Powder?

Definitely yes, there is no risk to dogs with kidney failure if powdered eggshell is added to their diet.

And studies have shown that a diet low in phosphorus slows the progression of kidney disease.

In general, the foods richest in phosphorus are bones, dairy products, fish, organ meats and egg yolks.

However, most dogs with kidney disease, liver disease, crystals or kidney stones need less calcium and an adequate calcium-phosphorus ratio.

And that is why the recommended calcium source for this type of diet is ground eggshells, because eggshells have a balanced ratio of calcium and phosphorus.

How much Eggshell Powder Should I Give my Dog?

It depends solely on the food you are feeding your pet and the amount of nutrients contained in those foods.

Here are some general recommendations for the exact amount of calcium your pet should have.

Approximately 1/8 teaspoon of powdered eggshell per 10 pounds of body weight, assuming they are not receiving calcium from other sources.

This indicates that a 4.5kg dog will need approximately 225mg of calcium per day.

1/8 teaspoon

225 mg calcium

per 10 pounds of weight

These are the guidelines according to the Association of American Feed Control Officials (AAFCO) for dogs

Cup Calcium content Dog weight
1/4 teaspoon
450mg 20pounds/9kg
1/2 teaspoon
900mg
40pouds/18kg
1 teaspoon 1800mg 80pouds/36kg

How Long Does Eggshell Powder Last?

Over the years, I have met countless dog owners (including myself)

who have fed their dogs eggshell powder after two months with no side effects.

Most expiration dates indicate freshness and when the product is at its peak, not necessarily that it is spoiled.

However, for safety reasons, I recommend that you respect the two-month expiration date.

Label your container and refrigerate to keep fresh.

Eggshell Powder FAQs

I have received several questions about eggshell powder. Please read on so that you can get the answer.

“Types Of Eggs to Use for Eggshell Powder”

My eggs are chemical free, as I usually buy them from a local farmer.

I do not recommend using store-bought eggshells for your pets.

Supermarkets bought eggshells are cleaned with chemical disinfectants to remove bacterial residue.

This is not something I want my pets to feed on.

If you must use store-bought eggshells, I recommend baking them at

300 degrees for about 7 minutes to remove any chemicals from the shells.

“Are There Any Risks with Feeding Eggshells?”

None that I have witnessed, heard or observed over the years.

When eggshell powder is properly prepared as directed, it is considered safe to eat.

There is a small chance that eggshells can be contaminated with bacteria such as salmonella.

The most effective way to avoid this risk is to boil the eggshells before grinding them.

The other risk is over-supplementation, which can lead to excess calcium in your pet’s diet.

“Can I Add Eggshells to Kibble?”

I could not recommend it in any way.

As mentioned repeatedly in the article, eggshell powder is completely unnecessary for commercial foods

that are already complete and balanced with the necessary vitamins and supplements your dog needs to meet all calcium needs.

Either way, adding more calcium to processed pet foods would only cause them to overdo it and also risks causing an imbalance in their diet.

Powdered eggshell is much more suitable and recommended for supplementing DIY raw dog food diets.

“What Quality of Eggs Should I Use for Eggshell Powder?”

The best quality you can afford.

Most of the research in this article is based on eggshells from traditionally raised hens, as they are the most suitable.

If you don’t have the means to afford free-range, organic eggs, you can opt for regular eggs.

They will still be a good source of calcium.

In any case, research indicates that conventional eggs have a higher level of calcium.

“What Should I Do with Eggshell Powder Past its Due Date?”

Powdered eggshell works as an excellent fertilizer for plants.

You can sprinkle and mix some eggshell powder into your garden soil and then add calcium carbonate to reduce the acidity of the soil.

You can also use eggshells for planting.

Another option is to add eggshells to the compost.

Calcium is a necessary nutrient because it helps plants build their cell walls.

Therefore, adding calcium to the compost will help plants grow.

You can also use leftover eggshells to create a non-toxic abrasive cleaner.

Simply mix one cup of eggshell powder with 3 cups of baking soda.

Clean up, mix the powder with vinegar and watch the magic happen.

Can I Feed the Whole Egg and Not Just the Shell?

We’ve already talked too much about eggshells, so what about whole eggs?

The short answer is yes, dogs can ingest eggs.

They are a beneficial protein source and nutritional supplement.

Still, we have a lot of questions regarding eggs for dogs, so we have answered some of your questions below.

Can Dogs Eat Eggs Raw?

Veterinarians typically advise cooking eggs before feeding them to dogs, but some owners opt for raw eggs.

However, there are potential issues to keep in mind with raw egg consumption, including the risk of dogs getting salmonella.

How Many Eggs Can a Dog Eat in a Week?

A whole egg a day, or even several eggs a week, is sufficient for most dogs.

Can Dogs Eat Cooked Eggs?

Yes, they can eat cooked eggs.

However, cooking causes a small loss of nutrients.

Cooked eggs scrambled in a little pastured butter are an excellent way to cook eggs to feed your dog.

Do not add an exaggerated amount of salt, nor too much seasoning.

The most feasible is a normal boiled egg.

“Can I Just Buy Eggshell Powder?”

Of course, it is.

Everyone at some point can get tired of DIY and it’s easier to buy it.
