A 51.6% ash figure looks alarming next to a food's usual single digits, until you remember a bone is mostly mineral, not meat, and that's exactly what it should be.

This is a slow-roasted, 100% British beef marrow bone, sold individually: the price shown is for one bone. It analyses at 39.6% crude protein, 9.2% crude oil and fat, 1.3% crude fibre and 51.6% crude ash — a composition typical of a genuine bone rather than a processed chew — and the guidance is no more than one per day, suitable for medium and large breeds over 6 months old.

• 100% British beef marrow bone
• Crude protein 39.6%, crude oil and fat 9.2%, crude fibre 1.3%, crude ash 51.6%
• Grain free
• Suitable for medium and large dogs over 6 months
• Feed no more than one per day
• Sold individually: one bone per item

On the ash figure. 51.6% crude ash is high compared with most treats, but that's expected for a genuine bone — ash on a label reflects mineral content, largely from the bone itself, rather than being a sign of anything gone wrong. Store it somewhere dry and cool, such as a garage or cupboard, rather than anywhere damp.

Who it's for: owners of medium and large dogs over 6 months who want a real, natural bone rather than a manufactured chew.
