Chew toys/edibles for 14 week old

My lil puppy is 14 weeks old and I am looking for some chew toys/bully sticks or edibles that’s safe for his puppy teeth. We have the blue Nyla bone, the ring toy, the one with the cloth tied to it. Our vet recommended some type of flexible cheese or bully sticks. Would you have any recommendations that would not fracture his tiny teeth.
