}}</ref>  Today, terriers are often informally categorized by size or by function.<!--categorization scheme needs to be documented-->

[[Working terrier|Hunting-types]] are still used to find, track, or trail quarry, especially underground, and sometimes to bolt the quarry.  Modern examples include the [[Jack Russell Terrier]], the [[Jagdterrier]], the [[Rat Terrier]], and the [[Patterdale Terrier]].  There are also the short-legged terriers such as the [[Cairn Terrier]], the [[Scottish Terrier]], and the [[West Highland White Terrier]], which were also used to kill small vermin.

The original hunting terriers include the [[Fell Terrier]] (developed in northern England to assist in the killing of foxes) and the [[Hunt terrier|Hunt Terrier]] (developed in southern England to locate, kill or bolt foxes during a traditional mounted fox hunt).

The various combinations of [[Bulldog breeds|bulldog]] and terrier that were used for [[bull-baiting]] and [[dog-fighting]] in the late 19th century were later refined into separate breeds that combined both terrier and bulldog qualities. Except for the [[Boston Terrier]], they are generally included in kennel clubs' Terrier Group. Breeders have bred modern bull-type terrier breeds, such as the [[Bull Terrier]] and [[Staffordshire Bull Terrier]], into suitable family dogs and show terriers.

[[Toy terrier]]s have been bred from larger terriers and are shown in the Toy or Companion group. Included among these breeds are the [[English Toy Terrier (Black & Tan)|English Toy Terrier]] and the [[Yorkshire Terrier]]. While small, they retain true terrier character and are not submissive "[[lap dog]]s".

Other descendants of the [[bull and terrier]] types, such as the Asian [[Gull Terrier]], are among the dogs still raised for dog-fighting.

=== Appearance ===
Terriers range greatly in appearance from very small, light bodied, smooth [[Coat (dog)|coated]] dogs such as the [[English Toy Terrier (Black and Tan)]], which weighs as little as {{convert|6|lb|kg|abbr=on|order=flip}}, to the very large rough-coated [[Airedale Terrier]]s, which can be up to {{convert|56|lb|kg|abbr=on|order=flip}} or more.  As of 2004, the United Kennel Club recognized a new hairless breed of terrier derived from the [[Rat Terrier]] called the [[American Hairless Terrier]].
