Yes, but only in some regions: in Piedmont, Lombardy and Liguria. In fact, only here there are no time limits for the truffle hunter, which can freely choose what time to go in search of truffles with his trusty dog. Some people prefer the night because the darkness allows them not to be seen by someone who could discover their secret truffle ground. And there are those who prefer the day because they love seeing their dog at work and want to enjoy all the research phases. In other regions the search is allowed only during the day, from one hour before dawn to one hour after sunset (a somewhat interpretable rule).
