The Blackdog Filled Cow Hoof with Peanut Butter is a single long-lasting natural chew for dogs of all breed sizes. It's a real bovine hoof with the hollow packed full of a peanut butter filling, aimed squarely at persistent chewers who blast through softer treats in minutes. Sold as a single piece rather than a multipack.

The hoof itself is a hard keratin structure, so it holds up to serious chewing without splintering the way cooked bones can. The peanut butter filling gives the dog a reason to keep working at it — licking and gnawing to get the flavour out — which is where the enrichment value comes from. Ingredients are minimal: bovine hoof, bovine meat and meal, glycerin, and peanut flour.

Owners pick this one for the heavy chewers — the dogs who need something to occupy them for more than five minutes. It's also a common choice for crate time or when you need the dog settled in one spot.
