As an enthusiastic dog-owner (for two weeks now), I enjoyed reading “Inside of A Dog: What Dogs See, Smell, and Know ” by cognitive scientist Alexandra Horowitz–I’m a sucker for airport bookshops. The author describes how humans have six million olfactory receptor cells while dogs have not only many more–as many as three hundred million–but they also have a much more robust neurological apparatus for detecting and interpreting the nerve signals that they send on to the brain.
So dogs smell better than we do, which is not news. Humans, though, have a much better grasp of the Fourth Amendment’s protection against unreasonable search and seizure. In 2013, the Supreme Court made some important decisions about the use of trained police dogs in establishing probable cause.
Comparing the use of sniffer dogs to the unwarranted use of thermal imaging, Justice Scalia wrote an opinion in Florida v. Jardines holding that police officers may not bring a drug-sniffing dog to your doorstep and use a canine response to establish probable cause for obtaining a warrant to search the home.
