Terrier Group is the name of a breed Group of dogs, used by kennel clubs to classify a defined collection of dog breeds. In general, a Terrier Group includes one particular type of dog, the Terrier, although other types may be included in a kennel club's Terrier Group. Most major English-language kennel clubs include a Terrier Group although different kennel clubs may not include the same breeds in their Terrier Group. The international kennel club association, the Fédération Cynologique Internationale, includes Terriers in Group 3 Terrier, which is then further broken down into four Sections based on the type of terrier and breed history.
Terriers were originally kept to hunt vermin, especially mice, rats, rabbits, otters, stoats and weasels. Some Terriers were designed to go down the holes of the European fox and other agricultural pest animals in order to chase them out for the hunter, and the name terrier is from the Latin terra, meaning earth, in reference to the dogs going underground. Today, the majority of modern breeds developed from the old terrier types are pets and companions. A few are still used as working terriers, and some terriers are large enough to be kept as guard dogs.
Kennel clubs assign breeds traditionally identified as terriers to their Terrier Group. Some kennel clubs prefer to use another category such as the Toy Group, Companion Group, Utility Group or Non-Sporting Group for certain terriers or terrier-like breeds, but most terriers are placed in the Terrier Group.
