A dog that works for a living burns through a bag of food faster than one that naps on the sofa, which is why working-dog ranges tend to run richer than the everyday shelf. Skinners built Field & Trial around that difference rather than trying to make one recipe suit both.

The recipe leads with poultry meat meal at a minimum of 95% chicken, making up 30% of the food, alongside sweet potato chips at 25%, potato flake, poultry fat, peas, whole linseed, beet pulp and brewer's yeast. It's grain-free, and it carries small measured additions of glucosamine (350mg/kg), chondroitin sulphate (150mg/kg), seaweed (150mg/kg) and yucca (100mg/kg) alongside a herb blend.

• Grain-free

• Energy content 355 kcal per 100g
• 15KG bag

On the joint additives. Glucosamine, chondroitin, seaweed and yucca are all on the label, but each one is present in milligrams per kilogram rather than as a percentage of the food — a few hundred milligrams in a 15kg bag. They're a genuine inclusion, not an invented one, but they're a small addition to the recipe rather than the main event.

Who it's for: owners of an active or working dog who wants a grain-free, chicken-based food built for higher energy demands, rather than a standard adult recipe.
