(Terrier Dog Breeds, Large, Medium-sized, Small and Toy Terrier Breeds)
Jack Russel Terrier
Terriers are typically small to medium-sized dogs, used for vermin-control and for hunting rats, rabbits, and foxes both over and under the ground. They are usually very active and excitable dogs, showing a proud and tenacious temperament. Many terrier breeds are used to working without human intervention and, as a consequence, need persistent and creative training techniques.

Etymology and Definition

Etymologically the word comes from the French chien terrier, based on the Latin terra firma, 'earth dog', referring to the fact that the terrier pursues its quarry into their burrows.

An exception to this is the Airedale Terrier, which is large in size and used for chasing down otters in and around water.

The term first appears in 1576, written as Terrar or Terrarius, in Johannes Caius' work De Canibus Britannicus (Of English Dogs). The term is used to describe fox and badger hunting dogs that pursue their quarries into the earth. The dogs belonging to this group are described as hunting dogs with an excellent nose.

Not included here in the Terrier group are the bull type terriers (such as the Staffordshire Bull Terrier, Amstaff, Boston Terrier, etc.) which descend from the ancient bull-and-terrier breeds and which were not usually utilized as vermin-controlling earth dogs.

The bull type terriers differ enough in physical appearance and temperament to be considered a separate group. The same goes for the Tibetan Terrier. However, terriers that were created purely as companion dogs, such as the Japanese Terrier, have nevertheless been included here, because their character and conformation remains close enough to the original working terriers.

ancestors of our modern Terriers
In the 19th century, terriers were not yet separated into distinct breeds as they are today.

In Cynographia Britannica
(published around 1800), Sydenham Edwards distinguishes two types of terrier: crook-legged and straight-legged.

Airedale Terrier: The Airedale Terrier (short "Airedale") named after the Aire valley, or Airedale, in Yorkshire, England, where it was used to hunt otters along the River Aire.

Russian Black Terrier: a recent breed of terrier, developed by the Red Star Army Kennels by crossing the Giant Schnauzer, Airedale Terrier, Rottweiler, possibly involving also other breeds. More about the Black Russian Terrier >>

Medium-sized Terriers

Bedlington Terrier: a breed of terrier with a non-shedding, wolly coat, originating from the mining town of Bedlington.

Brasilian Terrier: a game and vermin hunting breed, developed in Brazil from Jack Russell Terriers crossed with miniature Pinschers and possibly also Chihuahuas.
Until 1850, when controlled breeding began, all dogs that went to earth chasing foxes were called fox terriers, indifferently of their county of origin, and each English county had its own fox terrier. In his History of the Dog (1845) W.C.L. Martin recognizes only three types of Terriers: the smooth Terrier, the rough, wire-haired Scotch Terrier, and the long-haired, short-legged Terrier.

These early Terriers were usually black in color with tan markings above the eyes and on the muzzle and legs. Red, fawn and spotted terriers were commonly seen as well. White was the favorite color for hunting terriers, a color that enabled to distinguish them from the prey. Often, their tail was docked and their ears cropped.

Fox Terrier (Smooth): a terrier breed that descends from the now extinct Cheshire and Shrophire Terriers and the Beagle. The Smooth Fox Terrier has a smooth, flat, but hard and dense coat.

Fox Terrier (Wire): similar to the Smooth Fox Terrier, but with a dense, wiry, broken coat.
