I would switch Nutro as fast as possible.
I fed it for 2 weeks and while it didn't have any effects on Jackson... I got scared and didn't even want to risk it. I felt the same way at first like "Oh, it can't be that bad..." but I've learned a ton about dog nutrition through this board and my own research and I just would
never feed a food like Nutro again.
