‘The canine’s nose is a masterful creation,” Rebecca Frankel writes in this exceptionally interesting and surprisingly moving book; “all earthly schnozes are not created equal, anatomically speaking. While the average dog has roughly 220 million scent receptors in his nasal cavity, the average human has around 5 million.” Reading that, I flushed with pride on behalf of my rescue pooch, Clifford, whom I take on business trips several times a day but whose business consists more of sniffing (his name really should be Snifford) than of pooping.
