Lamb is often reached for as the single-protein option when chicken hasn't agreed with a dog, so it matters whether a "lamb" recipe is actually built around lamb or just flavoured to taste like it.

Lamb makes up 50% of this recipe, split between 26% fresh lamb and 24% dried lamb, alongside dried sweet potato at 25%, dried peas, beet pulp, rapeseed oil and lamb gravy. Small amounts of mannan-oligosaccharides, chicory root extract, dried botanicals and yucca extract are also included. Protein is 30%, crude fat 12%, crude ash 11% and crude fibre 5%, with a full vitamin and trace element panel added per kilogram. Forthglade describe it as grain-free and built around a single source of protein.

On "no junk fillers". Forthglade describe the recipe as containing no junk or cheap fillers, which is a fair characterisation of a food built on named meat and named vegetables rather than generic cereal — but it's their own marketing language, not a defined or measurable standard, so treat it as a description rather than a certification.

Who it's for: adult dogs of any breed on a single-protein diet, particularly where lamb has been chosen specifically over chicken or turkey.
