My bf was eating buffalo wings and got up to get a napkin and wasn't paying attention

and Meeko got a bone and swallowed it before we could grab him. What should I do? Just pray it passes ok? Get some peroxide and try to make him vomit? I'm kinda freaking out, I know they should have bones! I don't have peroxide so I need to know ASAP if I need to run to CVS to get some. I don't see any parts around so he ate a whole bone. He's not tiny tho, he's about 12 lbs. I just don't know if he'll be able to pass it.
