Pre-mades are sooooooooo easy! The convenience is a real time saver. I like Stella and Chewy's best. Then Primal, Bravo, and Natures Variety. You can either do the freeze dried or the frozen.
You could keep some ZiwiPeak on hand also. Another awesome food for puppies!
Once the puppy is settled on those, it's easy to throw in some meats to get chewing satisfaction and the benefits of the bones. I like cornish hens as the bones are small and easy to chew. You'll be surprised at how quickly puppies adapt.
As far as making sure her diet is balanced, just aim for 80% meat, 10% bones, 5% liver, and 5% other secreting organ such as kidney. Natures model is always best.
