Everyone knows the story of a boy and his dog is endearing. What about an old man and his dog? Better yet, old Italian men and their old Italian dogs? “The Truffle Hunters” (2021) is ostensibly a documentary about the quirky world of truffles – the prized tuber of haute cuisine. I still don’t know why they’re so expensive, but they’re dealt like drugs in back alleys at night, with buyers, sellers and middlemen all BS-ing each other. The emotional center of the story, however, is the hunter-dog bond. After, long, quiet interludes, we’re rewarded with priceless moments. Just like hunting.
