re: #974 ihateronpaul Dogs can spell better than humans not because they smell in 3-d which is impossible(the dog can only pick up odor molocules which come in contact with his nose so can’t form a 3d image since that requires a different sort of information) but because they have far more scent receptors in their nose and roof of mouth that they can detect much more minute traces. It is quite easy to fool hte trainer but virtually impossible to fool the dog which is where most idiots running drugs make the mistake.
