A dog or dogs are put into the entrance of a badger sett, or fox earth with the intention of pursuing or bolting the "quarry". The dog can be traced using electronic locators. Some "hard" terriers actually fight the "quarry" underground. For this reason terrier work is also known as "fox baiting". Once the terrierman knows the dog's location, he will dig down and then 'dispatch' the quarry if it isn't already dead. However, badger diggers may take the badger away for baiting.
The dogs used for underground work are generally small dogs that can get through a network of tunnels, called 'tubes'. The breeds used are terrier types - Jack Russell's, Wire Haired Terriers, Lakeland, Bedlington, and Plummer breeds.
Dogs which are put to work underground are called earth dogs. Dogs which hunt above ground are called running dogs.
Terriers can attack and rip apart animals underground needless to say some terriers get severely injured themselves. Even terriers who hold a fox at bay whilst it is dug out can attack and injure the fox. Either way, a fox can be “dug out” in a process that on many occasions has involved the suffocation of the fox – and sometimes the terrier. Those that are "dug out" are finished off by a shovel or heavy stick. Sometimes they are thrown to dogs alive. Many of these are taken home as 'trophies' for the dogs to play with.
Terrier dogs are also used to "bolt" after foxes, driving them out from their hiding spots and into nets covering the enterance of earths. Foxes that bolt into nets are sometimes used as bait for young terriers – a process known as “ragging”. How a fox dies when it bolts into nets will never be monitored – stabbed, shot, clubbed to death – its what ever takes a terrierman’s fancy.
Some people get a 'rush' from seeing their dog digging out. It gives them the power to decide whether a wild animal lives or dies. Many will take part in digging out competitions at hunt events. Many people who do it call themselves 'pest controllers' or 'terriermen' but it could be the lad up the road, but they all have one thing in common: They enjoy the 'thrill' of control over life or death.
