Have you googled Nutro? It's known to have caused severe illness & even death in many pets.
There's a sticky at the top of the Health & Diet forum that grades dog foods, and there are several good websites that analyze and discuss the ingredients. Some of the foods I like are Acana, Orijen, Nature's Variety, Innova, Wellness...... there are so many I can't name them all. You just need to find one that your baby likes and that you feel good about feeding.
When you're switching to a new food, make the change slowly. Transitioning to fast can cause stomach upset. Good luck!
