90 Day Gut Reset
Dr. Ian Billinghurst Formulated with Dr. Ian Billinghurst, B.V.Sc.Veterinary surgeon · Creator of the B.A.R.F. diet · Author of four books on natural pet nutrition

Why 90 days? Guts change slowly. Stools often shift first, and skin and coat take longer, so we ask you to wait until day 90 to judge it.
