A dog with a suspected food sensitivity is usually put through an elimination process, and the fewer proteins on the label to begin with, the shorter that process is. Eukanuba's answer here is to use exactly one animal protein — salmon — rather than the usual blend of two or three.

Freshly frozen salmon and salmon meal each make up 19% of the recipe, with potato, whole peas and sweet potato providing the carbohydrate rather than wheat. Fructooligosaccharides and mannanoligosaccharides — both natural prebiotics — sit at 0.25% and 0.15% respectively, and sodium hexametaphosphate is included as a dental additive.

• Single animal protein: salmon only, at 19% fresh and 19% meal
• Protein 24%, fat content 12%, crude ash 6.9%, crude fibre 2.6%
• Calcium 1.2%, phosphorus 0.9%, omega-6 3.6%, omega-3 1.2%
• Prebiotics FOS (0.25%) and MOS (0.15%) included for digestive support
• Daily feeding ranges from 85-100g for a 5kg dog to 560-650g for an 85kg dog
• 12KG bag

One thing worth knowing. Grain-free is not the same claim as hypoallergenic, and Eukanuba's own reasoning here is about limiting animal protein sources to reduce the risk of a reaction, not about ruling out every possible trigger — maize gluten and pea starch are both in the ingredient list. If a vet has already identified a specific allergen, check it against the composition before switching.

Who it's for: owners of an adult dog with a suspected or confirmed food sensitivity, or anyone wanting to simplify a dog's diet down to one clearly stated animal protein before trying anything more restrictive.
