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.
If your vet hasn't already told you to try Purina Pro Plan, they probably will. It's the brand Reddit's dog food community and veterinarians keep circling back to — for good reason.
