Lots of breeders wean their puppies onto raw. After all, it is what they eat in the wild. There is no "wrong age" to start raw.
We feed raw and we love it! Taycie will love it and you will love how great it is for her. I personally wouldn't feed Nature's Variety pre-made though, just because there have been some controversies in the past about the quality of meat. NV uses a denaturant in their food - it's a charcoal additive that marks the meat a grey-ish color so that humans know not to eat it. It's marked as "unfit for human consumption" which is not cool by me.. my babies get the best! The only company that I know of that for sure doesn't use a denaturant is Primal but I think that Bravo and Stella and Chewy's are also great brands.
