USA Today spotlights a hardworking gluten-detection service dog.
I don't suppose my dog could do that... it would be useful. But my problem with hidden wheat is in restaurant food, and I can't imagine taking my dog into restaurants.
Obviously gluten has a distinct odor that dogs can detect. Why can't someone develop an instrument that detects it? Of course, if this were practical, the customs service would have instruments to detect all kinds of contraband. Dogs are awesome!
