different dogs have different nutritional requirements - just like people do. that is why i can never answer people who ask "what is the best food for my dog".

old research that linked protein to kidney damage has been disproven, feeding even high amounts of protein to a normal, healthy dog isn't going to damage their kidneys.

however, that doesn't mean that every dog can tolerate highly concentrated dry dog food that contains a high protein percentage and only very little moisture. the reason for this is that the kidneys need water to function properly, and in a natural diet that's pretty much automatic with the moisture content of meat.

last but not least, there are many dogs out there who are predisposed to kidney problems and need specific dietary management, but that is most often more related to the phosphorus content rather than the protein content of the diet.


last but not least, dogs who eat a raw diet tend to have higher BUN and creatinine levels than dogs who eat commercial foods that contain high amounts of grain - which evo doesn't, so it wouldn't surprise me if the results were similar.

in a nutshell: yes it is possible that a particular food isn't ideal for an individual dog. the only way you can find out about this is trial and error and not skipping important parts of caring for your dog - such as periodic bloodwork.
