Comparing wet and dry dog food

Avoiding dog food confusion.

Analysis of a dried dog food and moist dog foods often leads to confusion (even with some vets) when comparing them.

For example, Luath Holistic Nutrition diet foods have a protein content of 18.5%, On the other hand moist dog foods may state a protein level of 8%, which appears to be much lower in protein.

The difference outlined above arises because of the moisture content of the food.

A dry food may be less than 10% moisture whereas a wet dog food may have between 75 and 80% moisture.

The true protein (or fat content ) must be calculated in a dry matter basis. [Begin Block]

Here are some insights and clarification in comparing wet and dry dog food.

Typical dog food analysis.

Typical moist food analysis:

  • Protein 8%
  • Fat 6%
  • Moisture 75% (dry matter is 25%)

Typical dry food analysis:

  • Protein 18%
  • Fat 8%
  • Moisture 10% (dry matter is 90%)

To calculate the actual protein and fat level in wet or moist dog food we must remove the moisture (water) and work with the dry matter (25%).

Moist dog food:
 Percentage of protein: 8÷25 x 100 = 32% protein on a dry matter basis.

Percentage of fat: 6÷25 x 100 = 24% fat on a dry matter basis

Dry dog food:
 Percentage of protein: 18 ÷ 90 x 100 = 20% protein on a dry matter basis.

Percentage of fat: 8 ÷ 90 x 100 = 8.8 % fat on a dry matter basis

Note that although, the moist food says it contains only 8% protein, when calculated on a dry matter basis the protein level is actually 32%.

This is the only way to realistically compare wet and dry dog food protein and fat levels. [End Block]
