Blackdog Chicken Filled Marrow Bone is a 5-inch natural beef marrow bone packed with a chicken-based filling, made for dogs who take their chewing seriously. Suited to all breed sizes, it's positioned as a long-lasting treat rather than a quick reward.

The bone itself is natural bovine marrow bone — hard enough to occupy strong chewers for an extended session. The filling combines chicken meal, bovine meat, and bone meal with glycerine. Nutritionally, it delivers around 20% protein and 1% fat. Ingredients are straightforward, with no artificial additives listed in the retailer data.

The appeal is the combination: a durable chew that also delivers flavour through the filling. Dogs that demolish softer treats in minutes tend to stay engaged with this format longer, and it doubles as a dental health aid through mechanical chewing action.
