I would definitely suggest pet insurance in case you need an obstruction surgery. That being said... supervise, supervise, supervise! The ONLY reason my dog has never eaten anything unwanted is because he's watched 100% of the time that he isn't crated. Also, everything that I don't want his mouth on gets put out of his reach.
As Coco said, antlers are AWESOME chew toys. I don't really get why but my dog loves them too and will just chew for hours. Bully sticks are great too but after a while it starts getting eaten quicker and quicker. I also have to supervise my boy with the bully sticks because once he gets them down to about 6 inches he tries to swallow them whole. I don't know if you have kongs but those are good too, especially for a teething puppy. You can smear some peanut butter on the end and then stick them in the freezer for a bit. My dog loves them! The cold rubber will feel good on the pup's gums and peanut butter is tasty.
