Perhaps only some elderly truffle hunters still believe that this is a method that gives more results to the search and think that not feeding the dog the night before can push it more in this activity. But in reality, if we think about it, how is it possible that the hungry dog, therefore not in full form and weak, makes a good job? The search is tiring and the dog must have the energy necessary to face the whole day without getting tired after a short time. It is good therefore not to hesitate in providing him with the nutrients he needs to get a good performance and put him in a good mood.
