End of last year I met Freddie, a trained truffle dog. What a super chap he is too. He came along with his owner Mark for a visit to our place and to see if this area was suitable for truffles. 
He received his training from Marion Dean who runs the Truffle Hunters Dog School in Witcombe, Somerset. The courses are available for anyone who wishes to bring their dog and it seems that almost any breed is suitable. Freddie was one on the youngest at six months and Marion said "she was amazed at how successful he was".
It seems as if this part of Lincolnshire may be just right for truffles as they are found on chalk or limestone under beech, oak, hazel or silver birch trees.
