A working breed puppy's joints are doing more growing, on more uneven ground, than a companion breed puppy's — which is the argument for a puppy food with joint-support ingredients built in from the start, rather than added later once a problem has already shown up.

Skinner's Field & Trial Puppy leads with poultry meat meal at a minimum of 95% chicken (30%), then maize, brown rice, poultry fat, naked oats, prairie meal, beet pulp, sunflower meal, whole linseed, dried egg, vitamins and minerals, brewer's yeast, cellulose and marine algae meal. On top of that base it adds MOS at 2,500mg/kg, FOS at 1,000mg/kg, a herb blend at 750mg/kg, glucosamine at 250mg/kg, chondroitin sulphate at 150mg/kg and seaweed at 150mg/kg.

• Crude protein 27%, crude fat 18%, crude ash 7%, crude fibres 3%
• Omega-3 fatty acids 0.91%, energy 386 kcal per 100g
• Poultry meat meal, minimum 95% chicken, at 30%
• Glucosamine, chondroitin sulphate and a herb blend added for joint support
• Described on the official page as a complete dry puppy food
• 2.5kg or 15kg sack

On the joint additions. Glucosamine and chondroitin at these levels are a preventative inclusion rather than a treatment for an existing joint problem — if your puppy already has a diagnosed joint issue, that's a conversation for your vet rather than something a food's ingredient list can address on its own.

Who it's for: owners of a working breed puppy who want a higher-protein growth food with joint support built into the recipe from the start.
