Well, my naive question would be… how do you know that the additional ingredients at the end of a list are all from a pre-mix, and not individually added to the food by the company/local manufacturer themselves?
THK is dehydrated food as well, not kibble. Maybe their process is different from NRG's. At any rate, I shot a message over to THK asking how they would respond to this article. I am curious about how they would respond, but honestly, I am not worried because I consider them one of the most transparent, ethical pet food companies that I know of… They've gone to the trouble to note discrepancies of 0.01% of some ingredient in their nutrient profiles -- indicates to me that they're extremely proactive about monitoring the quality of their product, no matter how it's made.
