Niece is a GM for Petco. She told me that Costco kibble is top 10 dog food.
Tank gets the lamb and rice or chicken and rice. If he's a good boy I will mix a 1/2 can of sardines in olive oil in his food. When we get the rotisserie chikens from Sam's or Costco he'll get scraps of that mixed in, too.
Little sh-t sometimes turns his nose up if I don't mix in real meat. Then he goes hungry until he figures out that's what he gets or he don't eat... and he eats it.
