yes he's Archie, my lagotto,
We go hunt truffles very often, i'm going to make some videos on my youtube channel about it,
normally i go from January to April to Bianchetto (tuber borchii) it's like tuber magnatum, less fragrant with a bit of garlic smell, much less valuable, but i like it with pasta and butter
from may to july at tuber aestivum, the most common
and from october to december for the most popular and expensive white truffle (tuber magnatum), but I go very little to white, it's very competitive, the other hunters are too aggressive and it often happens that they kill the dogs with poisoned food, because is very expensive, like 2000 $ kg for the hunters
