Hundreds of people from around the country are attending the National Canine Conference this week. As part of the event, 30 dogs and their handlers are trying for official certification as bedbug location canines.
The dogs and their owners are taking part in exercises in which they walk down a hallway lined with containers — some with bedbugs inside. The dogs have to pick the right containers to get certified.
Bedbug infestations are tough to eradicate. The apple seed-size critters have been found in hotels, movie theaters, retail stores and homes nationwide. Some are even developing resistance to insecticides commonly used to kill them.
