Did you know? Rot present in wood has a distinctive odor that can be detected by specially trained dogs. In particular, "rothounds" have been trained to detect the distinctive odor of rot produced by a fungus known as serpula lacrymans. Rothounds have been used for decades in several Scandinavian places to detect decay found at the bottom of wood telegraph poles. Nowadays, they are employed to detect rot in the wood of historical buildings.
