T. Forrest Roast Knuckle Bone

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 as a pack of 12. 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.

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, bought as a pack of 12 to have on hand.
