Summary
Tens of thousands of five-star Amazon reviews and premium ingredients at a mid-range price. Blue Buffalo's senior formula includes antioxidants, vitamins, and minerals specifically tailored for aging dogs.
Specifically formulated for dogs 10 and older, Royal Canin's Aging 10+ is the top vet pick for truly senior dogs. It's one of the few foods designed around the unique metabolic and joint needs of dogs in their final years.

Our take
Blue Buffalo hits the sweet spot between quality and cost. It's not as scientifically rigorous as Purina Pro Plan or Hill's, but for owners who want better-than-supermarket ingredients without a subscription or premium price, it's a solid pick.
When your dog hits double digits, generic 'senior' formulas aren't enough. Royal Canin Aging 10+ is what vets actually prescribe — it's built for the specific physiology of very old dogs.
