My 10 year old Golden Retriever eats anything. The vet says she is the picture of health and I have fed her always REGULAR food. Premium Edge (not for seniors), then Taste of Wild all flavors rotated. After that I have fed her the left over Origen and Acana that my German Shepherd puppy seemed to not be able to eat. Her dog friends are from ages 2 yrs old to 5 or 6 and she can outlast them some days. She keeps up with our 20 month old German Shepherd. I agree that they NEED the protein to keep them young and vibrant. It’ll be a long time before she eats senior food.
