I totally agree you must always do what you are comfortable with. I would never say any different.
My Bella is a gulper, many a times she's swallowed a biggish piece of wing/thigh but she always hacks it back up, chews it up a bit more to finish it.
I don't panic when this happens and leave her to do her thing, she just does a couple of big urges and the bone is back up. I wouldn't stress her or panic her at this time.
I may be wrong but my way of thinking is if it goes down, they can regurgitate.
Chicken bones providing they are not cooked are soft.
Marrow bones are much harder, my dogs work their teeth against them trying to get the marrow from the middle but they couldn't bite off a lump of bone as my dogs are small and their jaws are not that powerful. (+ the bone is too big for them to swallow).
Lamb bones from Morrisons are good too, they are soft enough for them to eat, as well as having to chew them for while.
My 3 love a bone, to me that's what dogs do. If anything happened I wouldn't change the way I feed them, as I believe it's species appropriate.
Just my opinion
