I second the Nut!
Are you feeding controlled portions? It looks like Orijen has about 478 kcals per cup. Using the calculator on the review side, if she was a bit heavy at 82 pounds, you’d feed her just under 2.21 cups of Orijen daily, assuming she got no other treats at all. Does that sound at all close to what she was getting?
Some foods that I think are great quality (quality proteins) and lower fat are Wellness Core Reduced Fat, Go! Senior and Orijen Senior. Maybe one of those foods would work for her.
