I know there are a lot of people who love bully sticks. I don’t use them simply because my dog turns his nose at them (I think he knows where they come from, LOL!!!).
I don’t think a raw bone would do much harm unless it was a big load-bearing one (shoulder, leg, etc). Possibly try giving him some chicken backs/necks, and even freezing them to make them last a bit longer.
I also like to stuff toys (good rubber that won’t tear, of course) with treats and peanut butter, then freeze. This keeps my heavy chewer busy for a long time 🙂
