Fish4Dogs Complete Wet: White Fish with Sweet Potato review

Our Excellent band takes the salmon, level with the typical wet adult food, while the white fish reads Good a step below it. That is a real gap and not a photo finish, so choose by richness and protein and let the placing follow.

Ingredients, as declared: White Fish (70%), Dried Sweet Potato (1%, equivalent to 4% Sweet Potato), Green Beans (1%), Salmon Oil (0.5%), Minerals, Yucca Extract (0.05%), Dried Seaweed (0.05%).

Fish at 70% leads both labels, and the analysis stands behind the headline: protein converts to 34.6% of dry matter in the salmon flavour and 47.8% in the white fish. The fish is doing the work here rather than dressing the label.

The vegetables are declared with unusual candour. The salmon flavour prints its dried carrot at 1% alongside the 9% of fresh carrot it stands for, and the white potato and sweet potato entries get the same treatment. A maker that puts percentages beside even its smallest ingredients is a maker expecting to be checked, which is the right attitude.

There is no grain in either recipe, and not much starch of any kind. Carbohydrate converts to 7.7% of dry matter in the salmon flavour and 19.6% in the white fish, either side of the 15.8% typical for wet food.

Salmon oil supplies the omegas, at 0.3% in the salmon flavour and 0.5% in the white fish. That second figure is worth registering, because it means the white fish recipe is not free of salmon.

Two trace entries round things off. Green lipped mussel appears in the salmon flavour at 0.05%, a fashionable joint ingredient at a level that makes it a nod rather than a dose. Enjoy it as an extra without leaning on it. Yucca extract sits at the same level, and its usual job is taking the edge off stool odour.

The added panel is short and every line is dosed: vitamin A at 2,250 IU, vitamin E at 26 mg, and a run of trace elements from zinc to selenium with the figures printed.

The lean one. White fish at 70%, with sweet potato and green beans behind it. It runs 93 kcal per 100g, fat at 15.2% of dry matter, and protein at 47.8% of dry matter, the higher of the pair. Portions run generous at this energy level, and the 0.5% salmon oil means it is not a salmon-free recipe.

Both flavours are £7.47 a kilo. Cans are 395g, available one at a time or in packs of 6, 12, 24 and 48.

Assuming about 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate), a 15kg adult dog in moderate condition needs roughly 613 grams a day of the salmon flavour. The white fish comes to 903 grams. That works out at £4.58 a day on the salmon and £6.75 a day on the white fish.
