The point with senior foods is that seniors do not need less protein than adult dogs, but many senior foods lower the protein. Senior dogs are less able to use the protein in their diet and may need as much as 50% more protein just to get the same amount out of it. It is important to give senior dogs high quality proteins so they get the most out of it and have less waste in the bloodstream. Lowering phosphorus is OK, but not necessary for seniors that don’t have kidney issues and it is often done at the expense of protein in the diet.
