AAFCO: Animal feeding tests using AAFCO procedures substantiate that Purina ONE True Instinct High Protein Formula With Real Chicken & Duck provides complete and balanced nutrition for maintenance of adult dogs (per manufacturer). Chicken is the first ingredient.

This dry kibble recipe leads with chicken ahead of chicken meal, soy flour, whole grain wheat and beef fat, weighed by pre cooking weight, with duck appearing further down the ingredient panel behind several grain and plant protein sources. The manufacturer markets it as a high protein formula with no animal by-product meal, no fillers and no artificial flavors or preservatives, and its adequacy statement here is the feeding-trial form, substantiated through AAFCO feeding tests rather than nutrient calculation alone. It ships in 3.8 lb, 15 lb and 27.5 lb bags, with a feeding table running from half a cup for a 3 to 12 lb dog up to five cups plus a third of a cup per additional 10 lb for dogs over 100 lb. Dogs who lose interest in a rotation often take it again with a single ingredient freeze dried topper crumbled over the top.
