Five is middle-aged for a big dog. It comes round quickly.
Large breeds age on a different clock. Five is genuinely middle-aged for a 40 kg dog — the equivalent of a small dog at eight or nine — and the grey muzzle usually arrives before anyone has thought of her as anything but young.
This is built for that earlier turn. Glucosamine and chondroitin continue the joint support, with tea polyphenols at 150 mg/kg and borage oil added against oxidative ageing. Crude ash drops to 5.9% from the adult food's 6.7%, easing the mineral load, while fibre rises to 2.6% with psyllium to keep a slowing gut comfortable. Protein stays at 26% — an ageing large dog loses muscle readily and cutting protein accelerates it. For dogs five and over, 26–44 kg.
Dehydrated poultry protein, rice, animal fats, wheat, wheat flour, maize flour, vegetable protein isolate (L.I.P. — protein selected for its very high digestibility), hydrolysed animal proteins, maize gluten, maize, vegetable fibres, beet pulp, fish oil, soya oil, yeasts and parts thereof, minerals, psyllium husks and seeds, fructo-oligo-saccharides, borage oil, marigold extract (source of lutein), hydrolysed crustaceans (source of glucosamine), hydrolysed cartilage (source of chondroitin). Additives (per kg) — Nutritional additives: Vitamin A 22,500 IU · Vitamin D3 1,000 IU · E1 (Iron) 41 mg · E2 (Iodine) 4.1 mg · E4 (Copper) 13 mg · E5 (Manganese) 53 mg · E6 (Zinc) 132 mg · E8 (Selenium) 0.09 mg. Technological additives: Clinoptilolite of sedimentary origin 10 g. Sensory additives: tea extract (source of polyphenols) 150 mg. Preservatives. Antioxidants.
Store in a cool, dry place, sealed. Use within six weeks of opening; decant the 15 kg. Keep her moving — two shorter walks beat one long one, and swimming is excellent for sore hips if you have access to it. A raised, supportive bed off a cold floor makes a visible difference. Yearly bloods from five, and mention any new stiffness to your vet rather than writing it off as age.

A guide, not a rule. Slightly higher than the adult food at every band — an older dog uses food less efficiently, not more. Split across two meals. Fresh water, always.
