I used to feed my bully Taste of the Wild salmon formula and unfortunately he broke out with bumps on his back and had goopy eyes. After i visit to the vet, i decided to change his food to Natures Variety Instinct salmon formula. The bumps went away and his began to clear up (not totally but better than before). After I ran out of that, i accidentally bough Natures Variety Instinct limited ingredient diet. It is still good, but after this bag I will go back to the NVI salmon formula. His coat looked great and he totally lost that stinky dog smell.
