Believe it or not, dogs are the latest weapon being used in the fight against bed bugs. Bed bugs are small, oval-shaped, flat insects that can be hard to detect. The nose of a bed bug dog has the ability to sniff out as little as one live bed bug or just one viable bed bug egg. The reason for this is that dogs have somewhere between 20 to 40 times the number of nasal receptors as humans, making it easy for them to detect even the faintest of odors.
