This is a picture of 12 week old Riley. I am continuously amazed at what dogs can be trained to identify. In this case moths and other pests that can potentially damage artwork.
“No technology is as powerful at detecting scents as the nostrils of dogs, which have long been trained to use their
superior schnozzes to sniff out explosives, cadavers, bed bugs, ants and cancer, among other things.”
