Sarah, true, I was looking at the BB Wilderness Senior Red Meat formula, which has lower protein and lower phosphorus than the Senior Chicken formula. The Red Meat one has the same phosphorus as the Holistic Select Senior. And I see about the protein. I supplement with raw and canned every once in a while, so Bruno’s protein amounts vary a bit, but he seems to be okay with it.
Also, keep us posted on how Holistic Select goes for your dogs. I would get a smaller bag first, to see if they would even eat it, and if there are any digestive issues with it before I go for the bigger bag.
