 Though inefficient, a team of terriers, when coupled with an enthusiastic digger, can control red fox, raccoon or groundhog on small farms where their presence might be a problem for chickens, geese, wild bird populations, and crop production.Because terrier work is selective, animals can be dispatched, or else they can be moved and relocated to nearby farms, forests or waste areas where they will do no harm.Terrier work, as it is known today, began with the rise of the Enclosure Movement in the late 18th Century in England.
