Sounds like she's doing wonderfully, Amy! I can't stop coming back to this thread. She's too adorable!

As far as the puppy vs. adult food thing goes, I've always been told that feeding a high quality adult kibble is better for pups than feeding puppy food. A friend of mine fed her pup adult Natural Balance (not sure of the formula but I don't think it matters). I'm sure Nebo and she will become great friends in time. Tango is much the same way as Nebo when puppies first arrive.
