BRIEF
HISTORICAL SUMMARY
: The Jack Russell Terrier originated in England in the 1800’s
due to the efforts of the Reverend John Russell. He
developed a strain of Fox Terriers to suit his needs for a dog to
run with his foxhounds and go to ground to bolt the fox and other
quarry from their dens. Two varieties evolved with basically
similar Standards except for differences, mainly in height and
proportions. The taller, more squarely built dog is now
known as the Parson Russell Terrier and the shorter, slightly
longer proportioned dog, is known as the Jack Russell Terrier.
GENERAL
APPEARANCE
: A strong, active, lithe working Terrier of great character with
flexible body of medium length. His smart movement matches
his keen expression. Tail docking is optional and the coat
may be smooth, rough or broken.
IMPORTANT
PROPORTIONS
:
·
The overall dog is longer than high.
·
The depth of the body from the withers to the
brisket should equal the length of foreleg from elbows to the
ground.
·
The girth behind the elbows should be about 40
to 43 cm.
BEHAVIOUR
/ TEMPERAMENT
: A lively, alert and active Terrier with a keen, intelligent
expression. Bold and fearless, friendly but quietly
confident.
HEAD
CRANIAL
REGION
:
Skull
: The skull should be flat and of moderate width gradually
decreasing in width to the eyes and tapering to a wide muzzle.
Stop
: Well defined but not over pronounced.
FACIAL
REGION
:
Nose
: Black.
Muzzle
: The length from the stop to the nose should be slightly shorter
than from the stop to the occiput.

: Tight-fitting and pigmented black.
Jaws/Teeth
: Very strong, deep, wide and powerful. Strong teeth closing to a
scissor bite.
Eyes

BODY
:
General
: Rectangular.
Back
: Level. The length from the withers to the root of tail slightly
greater than the height from the withers to the ground.
Loin
: The loins should be short, strong and deeply muscled.
Chest
: Chest deep rather than wide, with good clearance from the
ground, enabling the brisket to be located at the height mid-way
between the ground and the withers. Ribs should be well sprung
from the spine, flattening on the sides so that the girth behind
the elbows can be spanned by two hands - about 40 cm to 43 cm.
Sternum
: Point of sternum clearly in front of the point of shoulder.
TAIL
: May droop at rest. When moving should be erect and if
docked the tip should be on the same level as ears.

:
Shoulders
: Well sloped back and not heavily loaded with muscle.
Upper
arm : Of sufficient length and
angulation to ensure elbows are set under the body.
Forelegs
: Straight in bone from the elbows to the toes whether viewed
from
the front or the side.

(chestnut).
SIZE
AND WEIGHT
:
Ideal
Height : 25 cm (10 ins) to 30 cm (12 ins).
Weight
: Being the equivalent of 1 kg to each 5 cm in height, i.e. a 25
cm high dog should weigh approximately 5 kg and a 30 cm high dog
should weigh 6 kg.
FAULTS
:
Any departure from the foregoing points should be considered a
fault and the seriousness with which the fault should be regarded
should be in exact proportion to its degree. However, the
following weaknesses should be particularly penalised:
·
Lack of true Terrier characteristics.
·
Lack of balance, i.e. over exaggeration of any
points.
·
Sluggish or unsound movement.
·
Faulty mouth.
