Thankfully with Purina its all science. Thats part of the reason I love the company so much. I like the Sport 26/16 formula because my AmStaff has skin and stomach issues and that is the current formula that he does best on.
For a healthy dog with no issues, the sky is the limit. Since you are saying hes been picky as of late, you could try the Savor line. My dogs always go nuts for the shredded pieces of chicken in that line.
And now that he is an adult too if you really wanted to switch him to another brand you could. He is past the critical growth period of his life where you would want to feed a food like Purina to make sure hes getting proper nutrition. As long as the food says it is “complete and balanced” you can venture out to another brand.
