to clarify, i said this….” the unnecessary protein in the feed these days????? if anything it’s more HARMful, “….. i didn’t say it was more harmful [to the kidneys], HDM. nor did i mention any thing about renal failure. and as with all things, everyone has an opinion on the subject, based on one study or another, or, whose POV they find most convincing.
case in point: (in fact) 2 of the 5 footnotes on this very subject, in this site, are from the 1990’s, another is 7 years old. outdated to some, perhaps, but convincing to others… belief is a matter of choice

my source came from the 2010 edition of the Merek Vet Manual. http://www.merckmanuals.com/vet/management_and_nutrition/nutrition_small_animals/nutritional_requirements_and_related_diseases_of_small_animals.html#v3328611

but thank you for your opinion.
imo, if something in a dog’s body is not being utilized and due to the extra amount given, is causing something else in the dog’s body to overwork, to compensate for that, why even give it in the first place?

and best wishes to the op’s dog. hoping things have improved since july
