Terrier Group: What is it?
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.

People familiar with this Group invariably comment on the distinctive terrier personality. These are feisty, energetic dogs whose sizes range from fairly small, as in the Norfolk, Cairn or West Highland White Terrier, to the grand Airedale Terrier. Terriers typically have little tolerance for other animals, including other dogs. Their ancestors were bred to hunt and kill vermin. Many continue to project the attitude that they’re always eager for a spirited argument. Most terriers have wiry coats that require special grooming known as stripping in order to maintain a characteristic appearance. In general, they make engaging pets, but require owners with the determination to match their dogs’ lively characters. (AKC)
