Guaranteed Analysis Calculator

Compare Dog Food Based on Dry Matter Content

Because dry dog food has considerably less moisture than canned or frozen, you must convert both to a dry matter basis in order to compare the actual percentage of nutrients in each. Comparing food on a dry matter basis takes differences in water content out of the equation so nutrients are compared on a common basis. 

Be aware that the guaranteed analysis alone is not the only comparison you need to make. Protein can come from good or bad sources depending on the quality of ingredients used in the food.

We created this calculator to make it easier to compare nutrient values. Simply input the values from two samples you are comparing to convert both to a dry matter basis. The common formula is “% Ingredient Value/100% – X% Moisture X 100 = Dry Matter Basis %
