The only thing that concerned me about Orijen was the 40% protein, but even the Naturediet (once you've converted the protein level due to the moisture, etc) comes out at around 40% protein. I was told that the protein level is fine at 40% if the source is a high-quality, easily-digestible source such as meat. My spaniel has been fine on the 40% and his coat is far better than when I was feeding him the Burns. I still think Burns is a good quality kibble, but I feel too high in rice for my liking. This is why I began feeding the Naturediet alongside the Burns, but have recently changed to Orijen for Henry's breakfast. As I still have five boxes of Naturediet in the garage, he's having this for his dinner. Any other opinions on Orijen would be welcome!
