Dogs can sniff out C diff quickly and accurately whereas conventional lab testing costs a lot more and takes too long to get answers. A dog can "sniff out" and entire ward in less than 10 minutes! Dogs have been shown in the past to sniff out cancers as well as drugs, money, explosives, and even cell phones!
Dogs may be man's best friend, but they have a new found role in diagnostic medicine that is prectical and very valuable!
