What is crude fat in dog food?

Crude fat in dog food is an approximate amount of fat that is contained within the food before the food is digested. Because crude fat is not defined, the quality of the fat cannot be analyzed beyond the quantity it contains.

In pet food, crude fat is a debated topic because it cannot be checked for quality. Pet owners often wonder what sort of fat is being used, but do not get an answer from the food label on the pet food. A food containing high crude fat or low crude fat could contain any kind of fat, and therefore healthiness is hard to determine.
