1. Well, I've read two sides to this: that smoked are less stinky, but also that both are potentially dangerous:Woody Taylor said:

2. I think there's still some "filling" in the hoof.
Also, I have read the ingredients of some smoked dog products that evidently are marinated first, and there's sugar and salt and other stuff in that.
Some don't have those "extras."
I've been getting some "beef straps," which are tough back muscle, lightly smoked with no coating.
Mike S. gave me a link to a site with some good products. I can't find it right this minute, but that was where I got the "back straps."
