I've been doing some research on different foods for our new puppy. He's eating Nutro Puppy Lamb and Rice, but I think there are better foods out there. I'm considering Canidae or Innova. Is there a puppy formula for Evo? I haven't been able to find it. I still have half a bag of the Nutro left but want to introduce the new food slowly so I need to decide soon with the way he's eating! I also mix in a little cottage cheese and raw beef as the breeder recommended.
