Your Dog, the Gourmet

If he has such a sensitive nose, why is he eating your old socks?
Flavor is 80 percent smell and 20 percent taste. So does that mean dogs—which can pick up levels of TNT as small as a few parts per trillion, detect evidence of cancer in human urine, and sniff out the presence of health-threatening molds—have a better sense of taste than we do? And if they do, then why are they feasting on dirty socks? The answer to the question of what, exactly, dogs taste is not a simple one.
