Simple conclusion.... Dogs that are fed raw poop less can we agree? Anything that comes out of the body is considered waste can we agree? So...more poop means more waste right? Meaning there are ingredients in kibble that have no use or cannot be digested. The body takes what it needs...the rest becomes waste. But....if there is nothing there for the body to benefit from or has excess of unusable ingredients ...there is more waste. So...in raw feeding...the body is using most of the meat. Less waste! In kibble...the body is not using or cannot use the ingredients it contains...more waste! Anything in excess that the body doesn't need or is deemed unusable comes out as waste. Simply put.
