I have no experience with large breed dogs, I don’t know if they need anything special as adults. Senior dogs need a high quality higher protein food. Outside of Orijen senior, I think the rest of the senior foods are too low in protein. With an arthritic dog, I’d find a food without grains & potato as they can be inflammatory.

Is she getting joint supplements? Look into making Golden Paste for her. A large breed dog should be kept lean as opposed to too heavy; can you share a picture of her?
