There's an awkward stretch between a dog finishing its puppy food and being ready for an adult diet where neither quite fits — too old for puppy-level richness, not yet done growing enough for a maintenance recipe — which is the gap a junior food is built to cover.

Skinner's Field & Trial Junior leads with poultry meat meal at a minimum of 95% chicken (32.5%), then maize, wheat, brown rice, poultry fat, naked oats, beet pulp, whole linseed and vitamins and minerals, with marine algae meal, 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, seaweed at 150mg/kg and yucca at 100mg/kg. Skinner's own guidance is to feed it from around six months of age, or until your dog is fully grown.

• Crude protein 27%, crude fat 16%, crude ash 7%, crude fibres 2%
• Omega-3 fatty acids 0.94%, energy 384 kcal per 100g
• Poultry meat meal, minimum 95% chicken, at 32.5%
• Feed from around 6 months of age, or until fully grown
• 2.5kg or 15kg sack

On the age window. Skinner's guidance is to start around six months and continue until your dog is fully grown, but growth rate varies a lot between breeds — a large or giant breed will take considerably longer to finish growing than a small one, so "fully grown" is the actual marker to watch for, not a fixed age.

Who it's for: owners of a working breed dog between around six months old and full maturity, who want a food built specifically for that stretch rather than jumping straight from puppy to adult food.
