Joint ingredients on a food label are easiest to judge when their amounts sit beside the main recipe rather than being left as a front-of-bag promise.

Skinner’s Field & Trial Turkey & Rice is complete dry food for adult dogs, available in two bag sizes. Brown rice is 40.8% and turkey meat meal 26%, followed by naked oats, peas, whole linseed, poultry fat and beet pulp. The composition also declares glucosamine at 350mg/kg and chondroitin sulphate at 150mg/kg. Analysis is 24% protein, 11% fat, 6.8% crude ash, 3% crude fibre, 1.26% omega-3 and 353 kcal/100g.

• Complete dry food for adult dogs
• Two bag sizes
• Brown rice 40.8% and turkey meat meal 26%
• Glucosamine 350mg/kg and chondroitin sulphate 150mg/kg
• 24% protein and 11% fat

Keep the claim in proportion: the label declares joint-related ingredients, but this remains a complete food rather than a medicine. It also contains poultry fat and naked oats. Under 10kg: up to 150g daily; 10–20kg: 150–260g; 20–32kg: 260–400g; 32–45kg: 400–500g; 45kg and over: 450g or more. Feed dry or add a little water, keep fresh water available, and account for breed, size and activity level.

Who it's for: owners of adult working dogs wanting a turkey and rice recipe with declared glucosamine and chondroitin amounts, and a choice of smaller or larger bag.
