To have a meaningful comparison of pet food, you have to look at the guaranteed analysis numbers on a “Dry Matter Basis”. This simply means that you are evaluating the food as if it contained no water. Since water has no protein, fat or fiber you have to analyze the food with out water in the mix.
The Dog Food Adviser has written a very helpful article (Dry Matter Basis… the Only Fair Way to Compare Dog Foods) on the importance of Dry Matter Comparisons.
