I bought some hooves today for Nebo. I figured it would last longer. Yay! Those are great! They last a lot longer then rawhide, and he is more interested in them then other long lasting chews (such as booda/nylabones). He chewed on it all night, and it doesn't look much different. I didn't smell anything nasty with any of the stuff I got him. Of course I'm around smelly dogs all day long at work, so I guess I wouldn't notice it as much, huh? lol.
