The Scent Detectives

S1 E5: Dogs are born with an incredible sense of smell, and sometimes, we call upon these superpowers to help prevent ecological disasters, prevent the decline of endangered animals, and even sniff out a rare culinary delicacy. Join us as we follow canine detectives on the Canadian frontier working to the stop the advance of invasive zebra mussels, on the Western Cape to rescue geometric tortoises, and into the private woods of Washington to track down an aromatic fruiting fungus that's more expensive than gold: truffles.
