For the heavy chewer.

Goat horn first. Hard, hollow at the core, dense at the wall. Heavy chewers will work the inside of the horn for an hour before they get serious about the rest. Unlike split antlers, goat horn doesn't fracture into shards. The dog gets to work, you get to keep your floor.

Water buffalo horncore is a step up in density and a step down in price. It's the bone-dense interior of the horn — what's left after the keratin sheath comes off. Almost no smell. Most chewers we hear about take a week to get through one.

Olive wood is the curveball. Hardwood, no resin, no splintering, naturally bitter so the dog doesn't try to eat it whole. They gnaw, they chip off tiny shavings, the wood sands itself down. It's the closest thing in the catalog to a tree branch that won't fall apart.

Skip the marrow bones for these dogs — they crack teeth on cooked bones and choke on cut ones. Skip the rope toys completely. This is the kit when you've tried everything else.
