Raw Eggs for Dogs & Cats: Why We Recommend the Yolk, Shell & Membrane
Eggs have long been recognized as one of nature's most complete foods. Yet when it comes to feeding raw eggs to dogs and cats, there's no shortage of conflicting advice. Some people recommend feeding the entire egg, others suggest removing the whites, while many overlook the nutritional value of the shell and membrane altogether.
At The Raw Concierge, we look beyond eggs as simply another protein source. Instead, we view them as a concentrated whole-food supplement that delivers an exceptional combination of vitamins, minerals, healthy fats, structural proteins, and bioactive compounds that support overall health.
Here's why we recommend focusing on the egg yolk, shell, and membrane, and how to safely incorporate them into a raw-fed diet.
Why Eggs Are More Than Just Protein
While eggs certainly contain high-quality protein, that's not what makes them unique.
The greatest nutritional value comes from the diverse collection of naturally occurring nutrients found within the yolk, shell, and membrane. Together, these components provide compounds that support nearly every system in the body—from brain development and immune function to joint health and skeletal support.
Rather than viewing eggs as another meat source, we encourage raw feeders to think of them as one of nature's most nutrient-dense whole foods.
Why We Feed the Egg Yolk
The yolk is where the vast majority of an egg's nutrition is concentrated.
It naturally provides:
Choline
Vitamins A, D, E & K₂
Vitamin B₁₂
Biotin (Vitamin B₇)
Folate
Selenium
Phosphorus
Iron
Zinc
DHA
Arachidonic Acid
Lecithin
Phospholipids
These nutrients help support:
Brain development and nervous system function
Healthy liver function
Healthy skin and coat
Immune health
Reproductive function
Muscle maintenance
Eye health
Cellular repair
Choline: One of the Most Valuable Nutrients
One of the greatest nutritional advantages of egg yolks is their exceptionally high choline content.
Choline is essential for normal brain function, liver health, nerve signaling, and healthy cell membranes. Outside of organ meats, relatively few foods provide meaningful amounts of this nutrient, making egg yolks one of the richest whole-food sources available.
The Bird's Diet Matters
The nutrients inside an egg begin with what the bird eats.
Birds consuming diverse diets that include grasses, insects, seeds, and natural forage often produce eggs containing higher concentrations of beneficial nutrients, including carotenoids, omega-3 fatty acids, and fat-soluble vitamins.
This also influences yolk color.
Pale Yellow Yolks
Often reflect lower levels of carotenoid-rich foods in the bird's diet.
Golden Yellow Yolks
Typically indicate a more varied diet containing greater amounts of natural plant pigments.
Deep Orange Yolks
Often reflect diets richer in grasses, insects, and other carotenoid-containing foods, which may contribute to higher concentrations of naturally occurring carotenoids and fat-soluble nutrients.
While yolk color offers valuable clues, it should never be used as the sole measure of quality. A bird's overall diet is a much better indicator of nutritional value.
Why We Feed the Eggshell
Most people discard one of the most valuable parts of the egg.
Eggshell is an excellent source of highly bioavailable calcium carbonate while naturally providing trace amounts of:
Magnesium
Phosphorus
Potassium
Sodium
Strontium
Boron
Zinc
Copper
Manganese
These nutrients help support:
Healthy bones and teeth
Proper muscle contraction
Nerve transmission
Calcium balance
Homemade raw diets
When feeding shell, lightly crush or grind it before serving to make it easier to consume.
Why We Feed the Egg Membrane
Between the shell and the egg white is a thin membrane that many people never notice.
This overlooked layer naturally contains:
Collagen
Elastin
Glucosamine
Chondroitin Sulfate
Hyaluronic Acid
Dermatan Sulfate
Keratan Sulfate
These compounds support:
Joint health
Cartilage maintenance
Tendons and ligaments
Connective tissue
Skin elasticity
Recovery
Interestingly, eggshell membrane is commonly used to manufacture premium joint supplements because it naturally contains many of the same compounds those products are designed to provide.
Why We Don't Recommend Feeding Raw Egg Whites Alone
Raw egg whites naturally contain several protective compounds that serve important biological functions during embryo development.
Avidin
Avidin inhibits the absorption of biotin (Vitamin B₇), reducing its availability when raw egg whites are fed repeatedly by themselves.
Biotin plays an important role in:
Healthy skin
Coat quality
Fat metabolism
Protein metabolism
Fortunately, egg yolks are naturally rich in biotin, which is one reason we recommend prioritizing the yolk rather than feeding raw egg whites.
Protease Inhibitors
Raw egg whites also contain naturally occurring protease inhibitors, including ovomucoid.
These compounds can modestly slow protein digestion when fed raw. They're not inherently harmful—they simply exist to help protect the developing embryo.
Together with avidin, they're another reason many raw feeders choose to focus on the yolk, shell, and membrane.
Which Eggs Do We Recommend?
Not all eggs are nutritionally equal.
Whenever possible, prioritize:
Pasture-raised
Organic (when available)
Farm-fresh local eggs
Free-range
We primarily recommend:
Pasture-raised chicken eggs
Local farm eggs
Duck eggs
Quail eggs
How We Recommend Feeding Eggs
For the greatest nutritional value, we recommend feeding the following 3-4 times a week:
Egg yolk
Crushed eggshell
Egg membrane
Together, these components provide a diverse combination of naturally occurring nutrients that are difficult to replicate with isolated supplements.
Eggs can be served as part of a meal or, when appropriate for your pet's size and overall diet, as a meal on their own.
Can Puppies and Kittens Eat Eggs?
Yes.
Egg yolks naturally provide several nutrients that are especially valuable during growth and development, including:
Choline
DHA
Vitamin A
Vitamin D
B Vitamins
Essential fatty acids
Introduce eggs gradually and feed appropriate portions based on your pet's size and age.
Final Thoughts
When used thoughtfully, eggs are one of the most nutrient-dense whole foods you can include in a raw diet.
By focusing on the yolk, shell, and membrane, you're providing far more than protein—you are supplying a naturally balanced combination of vitamins, minerals, healthy fats, structural proteins, and bioactive compounds that support lifelong health.
Whether you're feeding pasture-raised chicken eggs, nutrient-rich duck eggs, or perfectly portioned quail eggs, choosing high-quality eggs and utilizing their most valuable components allows you to take full advantage of everything this remarkable food has to offer.
