Today I got my 11-week-old puppy a rawhide bone. I had held off on this for a while, having been given totally contradictory advice about appropriate toys and trying a number of others things first. I decided to watch him closely with it, and he bit off a small (~1x.5 inches) heavily-chewed piece and swallowed it before I could get it out of his mouth. I know the big worry is a blockage, and to watch for vomiting and failure-to-poop, but I'm worried. Any advice, words of wisdom, tips, or reassurance?
