that's just a skill issue, every time i got sniffed violently by cobb i just hop on the conveyer belt and run with the wind, keep a note that he's there, run other places. EZ
That doesn't change the fact that smelling is bad game design. It wasn't a problem until the last level where there isn't convier belt and he runs toward ant sound after the first battery I would stand still and not make a sound far away and he would still sometimes get me with luck
