A dull, dry coat is one of the more common things a bottle of oil in the kitchen cupboard is asked to fix, and salmon oil earns that job because it's essentially all fat — this one declares crude fat at 99.5%, with protein, fibre and ash all at 0.0%, because there is nothing else in the bottle to measure.

AniForte's oil is 100% salmon, carrying eicosapentaenoic acid (EPA) at 2.34%, docosahexaenoic acid (DHA) at 4.74% and alpha-linolenic acid (ALA) at 6.73%, adding up to a total omega-3 fatty acid content of 17.14% alongside 16.1% omega-6. Vitamin E is added at 1000 IU/kg as a natural preservative for the oil itself rather than as a headline supplement.

On the dosing. AniForte's own guidance is a teaspoon a day for every ten kilograms of a dog's bodyweight, and a quarter teaspoon a day for cats, mixed into the normal feed — an oil supplement isn't a medicine, but it's still worth checking with a vet before adding it daily alongside anything else your pet already takes.

Who it's for: owners of a dog or cat whose coat could do with more omega-3 and omega-6 in the diet, bought as a plain, single-ingredient oil rather than a blended supplement with other additions.
