Our friends are growing truffles in the NSW Southern Highlands and are yet to harvest their first crop. They have been told by the experts that truffles can only be found by strictly trained truffle dogs. These are hard living working dogs, not pampered house pets and must be treated as such. Yet a neighbour in the next valley has produced Australia’s second largest truffle and it was unearthed by their fat overfed blue heeler Jet. Jet the truffle dog. Good dog Jet.
