Is Hill's Science Diet worth it?
Strong for prescription and therapeutic needs, and that's genuinely where it belongs. For everyday feeding it's poor value: corn- and by-product-led panels at a vet-clinic price, with named-meat premium brands offering a better ingredient panel for the money. Don't default to it for a healthy dog without checking the cost per kg.

Better-value alternatives to Hill's Science Diet
Royal Canin
Super-premium
Worth it for genuine therapeutic and prescription needs, where the research is unmatched. For everyday feeding it's hard to justify: by-product- and grain-led panels at a top-tier price per kg, where much of what you're buying is the vet-clinic positioning. Compare cost per day against named-meat premium rivals before defaulting to it.
Prime100
Premium
A capable single-protein option for elimination diets, and the labels are honest. But the rolls especially carry a steep price per kg for what is a deliberately simple recipe, and the range spread across formats muddies value — price the dry against the rolls per serve before you settle on one.
Black Hawk
Premium
Fine on a discounted big bag if you choose a named-meat-first recipe, but don't assume the whole range is equal — the cheaper lines pad the panel with grain and rice, and a chunk of the price is reach and marketing rather than ingredients. Compare the specific formula on cost per kg against SavourLife and Ivory Coat.
