Fat Percentages in Pet Food: Why the Numbers on the Label Don't Tell the Whole Story

Fats in Your Pets Diet

Feeding your pet a raw food diet can provide numerous health benefits, such as improved coat quality, better digestion, and increased energy levels. However, one of the most critical aspects of this diet is balancing the fat content to ensure your pet receives optimal nutrition without adverse effects.

Why Fat Balance Matter

Fat is a vital source of energy for dogs and cats, providing more than twice the calories of protein or carbohydrates. It also supports healthy skin, coat, and cognitive function. However, too much or too little fat can lead to health issues:

- Excess fat can cause obesity, pancreatitis, or nutrient imbalances.

- Insufficient fat can lead to dry skin, poor coat quality, and energy deficiencies.

The key is to provide the right amount of fat for your pets ‘size, breed, activity level, and life stage.

Comparing Fat Content Between Pet Foods

Many of our customers ask us why the fat content in their bag of dry food is so different from the fat content of their wet/raw food.  The main reason is moisture. Because water dilutes the nutrients on the label, looking at the "Guaranteed Analysis" percentages side-by-side is like comparing apples to watermelons. 

To compare the fat content of dry food and raw (or wet) food accurately, you need to strip away the water.   The industry standard method to fix this is calculating the Dry Matter (DM) basis. This converts the nutritional percentages to what they would be if the food had 0% moisture.

1.Find the values on the label: Step 1.

Look at the "Guaranteed Analysis" panel on both pet food packaging. Note down the Crude Fat % and the Moisture % for both foods.

2.Calculate the total Dry Matter: Step 2.

Subtract the moisture percentage from 100 to find out how much actual dry matter (nutrients) is in the bag or container.

3.Convert the Fat to a Dry Matter basis: Step 3.

Divide the label's fat percentage by the dry matter percentage you found in Step 2, then multiply by 100.

 

Let's show how a raw diet that looks low-fat on the label might contain more fat than kibble once you adjust for water:

  • Dry Kibble Label: 12% Fat, 10% Moisture
    • Dry Matter =
    • Dry Matter Fat =  13.3% fat
  • Raw Food Label: 6% Fat, 75% Moisture
    • Dry Matter =
    • Dry Matter Fat =  24% fat

The Takeaway: Even though the raw food label says "6% fat" and the kibble says "12% fat," the raw food delivers almost double the fat content per pound of actual nutrients

Final Thoughts

Balancing fats in a raw diet is not just about avoiding extremes—it is about providing the right type and amount for your pet ‘s unique needs. Include a variety of fat sources by rotating proteins and including raw meaty bones. A well-balanced approach to fat can lead to a healthier, happier, and more vibrant pet.
