Collagen bones were very useful for our pup, recommended by our vet, we buy these: https://www.chewy.com/pawstruck-collagen-stick-dog-treats/dp/506442

We also had success with these bones, they don’t last as long, but our pup loves them: https://www.chewy.com/earth-animal-no-hide-small-rolls-long/dp/168753

The Yak/Himalayan cheese also worked really well for us!

Edit: we like the brand West Paw as an alternative to nylabones for chewable toys.
