Our take
Hill's Science Diet is the rare budget-friendly pick that doesn't compromise on science. It's vet-recommended, widely available, and has a senior formula that's hard to beat at this price point.
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.
