How Much Fat Should Be in Raw Dog Food?

Fat levels only make sense in the context of the overall raw feeding structure. If you’re not familiar with that yet, start with my basic raw dog food guide here.

Now, when I first started feeding raw dog food, I trimmed most of the fat, and I did it for Missy and Buzz, my two Boxer mixes.

I thought I was being careful. Responsible. “Health conscious.”

As I continued my education in raw feeding, I realized something: I had made their meals too lean.

Years later, with Wally and Pepper in the picture and hundreds of reader emails behind me, I don’t trim automatically anymore. I calculate, especially for dogs who need to lose weight.

Recently, one of my longtime readers, Frank, asked whether he should remove the skin from ground chicken when feeding his four small dogs.

After running the math together, the answer became clear: trimming wasn’t helping – it was lowering their energy density too much.

(And Frank later left a thoughtful tip in my virtual K9sOverCoffee tip jar after I helped him sort it out. Thanks again, Frank!)

So let’s talk about how much fat should actually be in raw dog food, because it may not be what you’ve been told.

Why Lean Raw Dog Food Isn’t Always Better

Many new raw feeders assume leaner equals healthier.

That assumption usually comes from human nutrition messaging, not canine physiology.

Dogs are metabolically designed to use fat as their primary energy source (as opposed to carbs). Protein builds tissue. Fat fuels the body.

When fat drops too low, you may start noticing:

• Reduced energy
• Duller coat
• Poor absorption of fat-soluble vitamins (A, D, E, K)
• Harder time maintaining healthy weight

In homemade raw diets, underfeeding fat is common, especially when visible fat is trimmed automatically.

How Much Fat Should Be in Raw Dog Food?

If you’ve heard that raw dog food should contain 10% fat, that guideline is overly simplified.

When formulating homemade meals, your muscle meat portion should average 15–25% fat, depending on your dog. These ranges apply to healthy adult dogs eating a properly balanced raw diet:

• 15% for low-activity or weight-prone dogs
• 20% for normally active adult dogs
• 25% for highly active or working dogs

This percentage applies specifically to the muscle meat portion – not the entire meal including bone and organs.

Fat is not an accessory nutrient in raw feeding. It is a structural component of proper formulation.

Important exception: Dogs diagnosed with pancreatitis or certain fat metabolism disorders may require significantly lower fat levels under veterinary supervision. In those cases, fat targets can drop well below 15%, and formulation must be individualized. Always work with your (holistic) veterinarian when adjusting fat levels for medical conditions.

Best Sources of Healthy Fats for Raw-Fed Dogs

When adjusting fat in raw meals, think in three functional categories:

1. Raising Overall Fat Percentage in Muscle Meat

Use these when your meat is too lean and you need to reach that 15–25% target:

• Beef trimmings or suet
• Chicken skin
• Fattier cuts like chuck or pork shoulder

These are efficient ways to increase caloric density and total fat percentage.

2. Supporting Omega-3 Fatty Acid Balance

These improve fatty acid ratios but are not typically used to significantly raise total fat percentage:

• Oily fish (herring, mackerel, sardines, lake trout)
• Fish oil
• Brains
• Eyes

Brains and eyes are fed as secreting organs and contribute DHA rather than bulk fat adjustment.

A practical guideline is about 1 oz of fish per pound of meat to improve Omega balance.

Green tripe also offers a more favorable fatty acid profile compared to conventional muscle meat, but it should be viewed as a digestive and micronutrient contributor first, not a high-fat adjustment strategy.

3. Supplemental Fat Contributors

These add moderate fat and valuable nutrients but are not primary fat-adjustment tools:

• Whole eggs (especially pastured)
• Egg yolks

Eggs contribute both fat and protein, making them excellent rotational additions, but they won’t dramatically shift your muscle meat fat percentage on their own.

Should You Remove Chicken Skin in Raw Feeding?

This is exactly what Frank asked.

For healthy dogs, removing chicken skin is often unnecessary.

Chicken skin is simply fat. And fat is fuel.

For small dogs eating limited daily ounces, trimming aggressively can quickly drop the fat percentage below optimal levels.

Instead of trimming automatically, calculate first.

How to Calculate Fat Percentage in Raw Dog Food

If your meat is too lean, you can calculate how much fat to add using the following formula. This is the same calculation method I use when adjusting fat levels for my own dogs and when helping readers troubleshoot lean diets.

Amount of muscle meat × (Fat target % − Current fat %) ÷ (100 − Current fat %)

Using 1 lb (16 oz) of muscle meat:

If you’re targeting 20% fat:

Ground chicken with 10% fat:
16 × (20 − 10) ÷ 90 = 1.8 oz added fat

Ground beef with 15% fat:
16 × (20 − 15) ÷ 85 = 0.9 oz added fat

Chicken breast with 3% fat:
16 × (20 − 3) ÷ 97 = 2.8 oz added fat

If you’re targeting 15% fat:

Ground chicken with 10% fat:
0.9 oz added fat

Ground beef with 15% fat:
No added fat needed

Chicken breast with 3% fat:
2.0 oz added fat

This is why calculating matters. The difference between 10% and 20% fat is not small, it’s metabolic.

Easy Ways to Add Fat to Raw Dog Food

If your muscle meat is too lean and falls below your 15–25% target, use efficient animal-based fat sources rather than plant oils.

Practical options include:

• Leaving chicken skin on
• Grinding beef trimmings or suet into your mix
• Choosing fattier cuts like chuck instead of extra-lean
• Including pork shoulder instead of pork loin
• Using higher-fat ground beef instead of 90/10 blends

These adjustments directly increase total fat percentage and energy density.

Omega-balancing ingredients like oily fish and organs such as brains support fatty acid balance, but they are not primary tools for correcting overall fat percentage.

Animal fat is species-appropriate and metabolically efficient for dogs.

Remember to take a look at the fat content of your muscle meats when you buy them!

Can Raw Dog Food Be Too Lean?

Yes, and it can happen more easily than many people realize.

Many raw feeders trim visible fat automatically out of caution. Over time, that habit can create a chronically under-fueled diet.

A balanced raw diet isn’t low fat. It’s appropriate fat.

If you’re unsure, run the numbers.

That small shift from trimming instinctively to calculating intentionally makes all the difference.

FAQ: Healthy Fats in Raw Dog Food

How much fat should be in raw dog food?

The muscle meat portion of a homemade raw diet should average 15–25% fat. Low-activity dogs do well around 15%, normally active adult dogs around 20%, and highly active dogs up to 25%. Fat provides energy and supports vitamin absorption and hormone function.

Is chicken skin bad for dogs?

No. Chicken skin is simply a natural fat source. Unless a dog has pancreatitis or a diagnosed fat intolerance, leaving the skin on can help achieve proper fat levels when feeding lean poultry.

What happens if raw dog food is too low in fat?

Diets that are too lean may lead to lower energy, dull coat, and reduced absorption of fat-soluble vitamins. Many homemade raw diets unintentionally fall below optimal fat levels when visible fat is trimmed excessively.

Can dogs with pancreatitis eat high-fat raw diets?

Dogs diagnosed with pancreatitis often require lower-fat diets under veterinary supervision. In these cases, fat levels may fall below the typical 15–25% range used for healthy dogs. Fat adjustments for medical conditions should always be individualized and monitored by a veterinarian.

Raw feeding is not about guessing, it’s about understanding how to feed the dog in front of you.

When you calculate instead of trimming blindly, you stop reacting to raw feeding myths and start feeding intentionally.
