We feed our Hooey NVI-Duck & turkey meal. When we got him we were feeding Purina Pro Plan (I know, uneducated parents ) until we realized how bad he was suffereing from allergy issues. He did a complete 180 when we first switched him. His "hot spots" were clearing up, he no longer had runny stools, the area around his mouth was no longer red, & it makes his coat EXTRA soft! I still suspect some sort of mild food allergy to the NVI because Hooey's tear stains are still rather bad & he occasionally licks at his paws, but all around it did wonders for him!
