Mars Petcare

The vet-clinic heavyweight, and the clinical research genuinely is best-in-class. But the everyday ingredient panels don't match the price: they lean on by-product meals, corn and grain rather than named single-source protein, and you're paying a high price per kg for the brand's vet-clinic shelf presence and breed-specific marketing as much as for what's in the bag. The therapeutic lines earn their keep; the standard ranges are expensive for the ingredient quality.

Hill's Science Diet

Hill's Pet Nutrition (Colgate-Palmolive)

A science-led brand with a deep, well-researched prescription range — clinically rigorous and consistent. Outside the therapeutic lines, though, the value is below average for the price: the standard panels lean on corn, grain and by-product meals rather than named single-source protein, and you carry a vet-clinic price premium for the brand and its shelf presence. The prescription range is the reason to buy it, not the everyday food.

Premium · Good

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.

Premium · Good

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.
