A truffle hog is any domestic pig used for locating and extracting the fruit bodies of the fungi known as truffles from temperate forests in Europe and North America. Pigs have an exceptional sense of smell, and are able to identify truffles from as deep as three feet underground. It is thought that the natural sex hormones of the male pig are similar to the smell of the truffles, [1] and, also, pigs have a natural affinity for rooting in the earth for food. However, they are trained to hunt truffles by walking on a leash through suitable groves with a keeper. [2]



The use of pigs to hunt truffles is said to date back to the Roman Empire, but the first well-documented use comes from the Italian Renaissance writer and gastronomist, Bartolomeo Platina, in the 15th century. [2] Later references to truffle pigs include John Ray in the 17th century. [2]

In 1875, a truffle hog could cost up to 200 francs. [3] A skilled truffler could more than make up for this investment from the high price of truffles on the gourmet food market. Today, dogs (known as "truffle hounds") are commonly used for gathering truffles in place of truffle hogs, as pigs have been known to eat too many truffles in the field. [4] Unlike pigs, dogs have no natural affinity for truffles, and must be specially scent to locate them. A trained Lagotto Romagnolo (an Italian breed recognized for its truffle-finding capability) can cost up to $10,000. Stealing such dogs is a common crime among rival hunters. [5] 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 a family pet of the truffler.

In Italy, the use of pigs in truffle hunting has been prohibited since 1985, as the animals can cause damage to the mycelia of truffles while digging, reducing the production rate for a number of years.

The beagle is a breed of small scent hound, similar in appearance to the much larger foxhound. The beagle was developed primarily for hunting hare (beagling). Possessing a great sense of smell and superior tracking instincts, the beagle is the primary breed used as a detection dog for prohibited agricultural imports and foodstuffs in quarantine around the world. The beagle is intelligent. It is a popular pet due to its size, good temper, and a lack of inherited health problems.

Fox hunting is an activity involving the tracking, chase and, if caught, the killing of a fox, traditionally a red fox, by trained foxhounds or other scent hounds. A group of unarmed followers, led by a "master of foxhounds", follow the hounds on foot or on horseback.

Scent hound Dog type, hunting dog

Scent hounds are a type of hound that primarily hunts by scent rather than sight. These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among dogs. Scent hounds specialize in following scent or smells. Most of them tend to have long, drooping ears and large nasal cavities to enhance smell sensitivity. They relatively need to have high endurance to be able to keep track of scent over long distances and rough terrain. It is believed that they were originally bred by the Celts.

Truffle Fruiting body of a subterranean fungus

A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus Tuber. In addition to Tuber, many other genera of fungi are classified as truffles including Geopora, Peziza, Choiromyces, Leucangium, and over a hundred others. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including Rhizopogon and Glomus. Truffles are ectomycorrhizal fungi, so are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance.

Feral pig Any type of feral domesticated pig, wild boar, or hybrid found world wide

The feral pig is a domestic pig which has gone feral, meaning it lives in the wild. They are found mostly in the Americas and Australia. Razorback and wild hog are Americanisms applied to feral pigs or boar-pig hybrids.

Detection dog Dog that is trained to use its senses to detect certain substances or items

A detection dog or sniffer dog is a dog that is trained to use its senses to detect substances such as explosives, illegal drugs, wildlife scat, currency, blood, and contraband electronics such as illicit mobile phones. The sense most used by detection dogs is smell. Hunting dogs that search for game, and search dogs that work to find missing humans are generally not considered detection dogs. There is some overlap, as in the case of cadaver dogs, trained to search for human remains.

Medieval hunting

Throughout Western Europe in the Middle Ages, humans hunted wild animals. While game was at times an important source of food, it was rarely the principal source of nutrition. All classes engaged in hunting, but by the High Middle Ages, the necessity of hunting was transformed into a stylized pastime of the aristocracy. More than a pastime, it was an important arena for social interaction, essential training for war, and a privilege and measurement of nobility.

Working animal Domesticated animals for assisting people

A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are beasts of burden that provide transportation and aid in physical labor, while others are service animals trained to execute certain specialized tasks. They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or other products such as leather.

Blue Lacy Dog breed

The Lacy Dog or Blue Lacy Dog is a breed of working dog that originated in the State of Texas in the mid-19th century. The Lacy was first recognized in 2001 by the Texas Senate. In Senate Resolution No. 436, the 77th Legislature honored the Lacy as "a true Texas breed." In 2005, in House Concurrent Resolution No. 108, the 79th Legislature called the Lacy "a Texas original; the only dog breed to have originated in this state." In June 2005, Governor Rick Perry signed the legislation adopting the Blue Lacy as "the official State Dog Breed of Texas" [need citation]. As expected, the vast majority of Lacy dogs are found in Texas. However, as the breed becomes more well recognized, there are breeding populations being established across the United States, Canada, and most recently in Europe.

Tyrolean Hound Dog breed

The Tyrolean Hound is a breed of dog that originated in Tyrol also called the Tiroler Bracke or Tyroler Bracke. They are scent hounds that descended from the Celtic hounds in the late 1800s, mainly for their hunting skills. They are hardworking, passionate, and independent dogs not known for their size, but rather their intelligence. For that reason, hunters can regularly use these dogs to catch their prey, wounded or otherwise. Their ability to stretch over long distances, on rough hot or cold terrain for their prey is also another perk of keeping this dog by your side. Hunters do have to worry about injuries to their dog, however, along with the common injuries that these dogs obtain throughout their life, like hip dysplasia or ear infections. Barring any injuries, these dogs tend to live an energetic life for about 12-14 years, and tend to be an overall healthy and robust dog.

Coon hunting Practice of hunting raccoons

Coon hunting or coon hunting is the practice of hunting raccoons, most often for their meat and fur. It is almost always done with specially bred dogs called coonhounds, of which there are six breeds, and is most commonly associated with rural life in the Southern United States. Coon hunting is also popular in the rural Midwest. Most coon hunts take place at night, with the dogs being turned loose, trailing and putting the raccoon up a tree without human assistance. Once the raccoon is in the tree, with the dog at the base, it is referred to as "treed", with "treeing" being the active verb form.
