Hi dan g,
You said “With the insurgence of grain free (more protein) foods also comes an increase of kidney failure at vets. So far, they still debate the cause as high protein or phospherus.” Could you please link where you got this information from.
As far as any studies I’ve read there is no link between high protein and kidney failure. Putting a healthy dog on a low protein diet to avoid kidney failure is very old,
outdated information.
Phosphorus, not protein needs to be bound and/or only when kidneys are failing, and not necessarily in the beginning stages. Grain free does not necessarily equate to high protein. BTW, Merrick canned classics are all grain free, they have been for a while now. I’ve fed them for years. I also have had a CRF dog, so I had to learn a lot about it.
