e/Truffle hog

Information
has gloss	eng: The truffle hog or truffle pig is a domestic pig used for extraction of truffles from temperate forests in Europe and North America. The pigs have a good sense of smell and a natural affinity for rooting in the earth for food, and are trained to hunt truffles by walking on a leash. Later references to truffle pigs include John Ray in the 17th century. . A skilled truffler could more than make up for this investment due to the high price of truffles on the gourmet food market. Today it is common for dogs (known as "Truffle hounds") as well as truffle hogs to be used in the gathering of truffles because hogs have been known to eat too many truffles in the field. However, traditionalists argue that the swine have more sensitive noses and their particular taste for truffles leads to a more devoted beast. It is frequent for the hog to be more of a family pet of the truffler.
