Hidden Nutrient Gaps in Raw Feeding: Building Balance Beyond 80/10/10
Raw feeding can be an incredible way to nourish dogs with fresh, species-appropriate food—but one of the biggest misconceptions in homemade feeding is that prey ratios alone guarantee nutritional balance.
An 80/10/10 raw diet can be a solid foundation:
80% muscle meat (including heart, which is a muscle meat)
10% secreting organs (including liver, kidney, spleen, pancreas)
*10% edible bone
But true nutritional balance goes beyond percentages.
Because even a well-structured raw diet can still leave nutritional gaps if important trace minerals, essential fats, and cofactors are overlooked.
Often, the first signs are subtle.
You may notice:
Dull coat
Itchy skin
Weak structure
Low stamina
Slow recovery
Chronic skin or ear issues
Loose stools
Ligament weakness
Growth concerns in puppies
Sometimes those signs may reflect nutrients imbalance.
Balance Starts With the Foundation
Before adding “extras,” the daily foundation matters.
Your 80/10/10 Should Include These Daily
80% Muscle Meat
Rotate protein variety:
Beef
Turkey
Chicken
Lamb
Rabbit
Pork
Fish
Heart (counts as muscle meat, not organ)
10% Secreting Organs — Fed Daily as Part of the Diet
This isn’t an occasional add-in.
These belong in the everyday balance:
Liver
Kidney
Spleen
Pancreas (optional rotation)
A common approach:
About half the organ portion as liver
The remaining half from kidney, spleen, pancreas or other secreting organs
These provide:
Vitamin A
Copper
B vitamins
Iron
Selenium
Zinc
Folate
They are foundational nutrition not supplements.
10% Edible Bone
Examples:
Chicken necks
Wings
Turkey necks
Ground bone
Boneless feeding? Use:
Eggshell
Balanced calcium replacement
Don’t Forget Daily Omega-3 Support
Another nutrient often underfed is omega-3.
Rather than treating omega-3s as occasional extras, many raw feeders choose to provide daily omega-3 support, especially when feeding land-animal proteins.
Include daily through:
Whole oily fish in rotation
Fish oil
Algae oil
Sardines when used in meal rotation
Omega-3s support:
Skin and coat
Joints
Brain and eye health
Anti-inflammatory balance
Immune function
And when feeding added fish oil, remember vitamin E support matters too.
Common Nutrient Gaps Beyond the Base Diet
Even with a strong 80/10/10 foundation, these nutrients can still deserve attention.
Calcium
Why it may run low
Often from boneless raw feeding or improper calcium-phosphorus balance.
Support with:
Raw meaty bones
Eggshell (for boneless meals)
Sardines with bones
Aim for: Calcium:
Phosphorus ratio around 1:1–1.2:1
Vitamin D
Can run low when fish intake is inadequate.
Food sources:
Oily fish
Egg yolks
Liver
Important cofactors:
Magnesium
Vitamin K2
Zinc
Zinc
Often one of the biggest raw-feeding gaps.
Low zinc may show up as:
Skin issues
Hair thinning
Poor wound healing
Dull coat
Food sources:
Beef
Lamb
Kidney
Liver
Oysters
Mussels
Pumpkin seeds
Vitamin E
Often overlooked in homemade diets.
Supports:
Muscle health
Immunity
Oxidative protection
Food sources:
Egg yolks
Fish
Sunflower seeds
Especially important alongside fish oils.
Manganese
A major overlooked nutrient in homemade raw diets.
Supports:
Ligaments
Tendons
Joints
Skeletal development
Food sources:
Green tripe
Mussels
Pumpkin seeds
Leafy greens
Nettle or parsley
Iodine
Frequently missing in homemade diets.
Food sources:
Kelp (small measured amounts)
Sea vegetables
Fish
Balanced iodine matters for thyroid health.
Symptom Clusters: What Your Dog May Be Telling You
Skin & Coat Issues
Think:
Zinc
Vitamin E
Omega-3s
Vitamin A
Selenium
Support with:
Fish or algae oil
Organs
Eggs
Seeds
Weak Structure or Joint Concerns
Think:
Calcium
Vitamin D
Manganese
Magnesium
K2
Support with:
Bones
Fish
Greens
Manganese-rich foods
Low Energy or Poor Recovery
Consider:
Iron
Copper
Selenium
B vitamins
Protein diversity
Support with:
Red meat rotation
Organs
Eggs
Seafood
Nutrient-Dense Foods Worth Feeding Regularly
These help cover common gaps:
Include routinely:
✔ Liver ✔ Kidney ✔ Spleen ✔ Heart ✔ Egg yolks ✔ Green tripe ✔ Mussels or oysters ✔ Leafy greens or pumpkin ✔ Small measured kelp ✔ Fish or algae oil daily
Think of these as foundational foods, not occasional “boosters.”
Food First… But Balance Still Matters
Whole foods can do a tremendous amount.
But puppies, breeding dogs, seniors, and orthopedic-risk dogs often need even tighter nutrient balancing.
That’s where professional formulation can be valuable.
Final Thoughts
Raw feeding is about much more than prey ratios.
It’s about complete nutrition over time.
And some of the biggest gaps in homemade diets often aren’t protein-related at all—they’re trace mineral and cofactor related:
Iodine
Manganese
Zinc
Vitamin E
Omega-3s
Selenium
Magnesium
Vitamin K2 support
Start with a solid 80/10/10 foundation.
Feed liver, kidney and spleen as part of that daily organ portion.
Feed omega-3 support daily through fish or algae oil.
Then build variety around that.
Variety builds resilience. Balance builds health.
