My boys are both super aggressive chewers, but thankfully they can live without chews -- they don't turn to things they aren't supposed to chew. Still, I wish I could give them something I feel really good about and don't have to supervise to the point of holding the chew myself.
I stopped giving them ingestible chews over a year ago because of the health hazards/recalls. Max chipped a tooth on a Himalayan.
The only thing we still use on occasion are CET chews, which I hold while they chew and do not let the boys eat. We buy the mediums which are supposed to be impossible for smaller dogs to get a piece off of, but Mr. Teddy-Scissors-Teeth can do it. Max turns them into something resembling a wet potato chip and a choking hazard rather quickly.
Max chews on soft toys daily. I keep a close eye on the toys to make sure he isn't getting stuffing out. The ugly toys I make out of tightly woven polyester last the longest.
Both of the boys will gnaw on the Extreme Kongs (without any treats). Teddy finally killed one of our 3-year old Kongs.
The Dura Chew Nylabones, we tried when Max was younger and he gnawed off shards and made them into sharp dangerous things. We tried different styles and had the same result.
I wouldn't trust my guys with any kind of real bone. They would definitely crack their teeth.
I wish I had normal chewers.
