The amount of time and money spent detecting C. diff and other healthcare associated infections is an obstacle to prompt treatment. This smart (and very cute) video shows that dogs could very well be the answer to detection. In the Netherlands, a team has trained a beagle named Cliff to sniff out C. diff among patients even hours after their last bowel movement.
Peggy was a dog lover through and through. I imagine seeing this little guy work brings her joy.
