What dog toy is actually safe for aggressive chewers?

No toy is truly indestructible, and the specialist subreddits we read are blunt about that. Hard nylon chews like the Benebone Wishbone and dense natural-rubber balls get the most consistent praise across r/dogs and r/puppy101, but vet-tech threads also flag tooth-fracture risk on very hard chews. Most reviewers recommend supervised chewing and replacing toys at the first sign of cracking or sharp edges.
