I agree with Ann- if you are going with Nature's Variety, start with the organic chicken. The other meats can be a bit rich. I feed Primal raw, which I prefer because of the organic, free-range proteins. These proteins are only fed from US sources and nothing is used from China
I switched cold turkey. I fed exclusively raw for months, and the transformation I saw in Ryder was unbelievable. I now feed kibble for snacks and travel, and raw for meals. They are done really well that way.
