What it is

Chicory root fibre, rich in inulin, a fructan the dog cannot digest but its gut bacteria can. Inulin and FOS on a panel are the same idea in purified form.

Why makers use it

A prebiotic: it feeds the bacteria rather than the dog, shifting the gut population toward fermenters that produce useful metabolites.

What to watch for

Too much, too fast, ferments to gas. In normal panel positions it is a quiet quality signal.
