Country of development : Australia
Date of publication datum of the original valid standard :
25-10-2000
UTILIZATION :
A good working terrier with ability to go to ground. An excellent
companion dog.
CLASSIFICATION FCI :
Group 3 : Terriers
Section 2 : Small Terriers
With working trial.
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
CRANAL REGION :
Skull : The skull should be flat and of moderate width gradually
decreasing in width to the eye 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..
Lips : Tight-fitting and pigmented black.
Jaws/Teeth : Very strong, deep, wide and powerful. Strong teeth
closing to a scissor bite.
Eyes : Small dark and with keen expression. MUST not be prominent
and eyelids should fit closely. The eyelid rims should be
pigmented black. Almond shape.
Ears : Button or dropped of good texture and great mobility.
Cheeks : The cheeck muscles should be well developed.
NECK :
Strong and clean allowing head to be carried with poise.
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 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.
LIMBS
FOREQUARTERS :
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.
HINDQUARTERS :
Strong and muscular, balanced in proportion to the shoulder.
Stifles : Well angulated.
Hock joints : Low set.
Rear pastern (Metatarsus) : Parallel when viewed from behind while
in free standing position.
FEET :
Round, hard, padded, not large, toes moderately arched, turned
neither in or out.
GAIT/MOVEMENT :
True, free and springy.
COAT :
Hair : May be smooth, broken or rough. Must be weatherproof. Coats
should not be altered (stripped out) to appear smooth or broken.
COLOR :
White MUST predominate with black or tan markings. The tan
markings can be from the lightest tan to the richest tan (chestnut).
SIZE AND WEIGHT :
Ideal Height : 25 cm (10 ins) tot 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.
N.B. :
Male animals should have two apparently normal testicles fully
descended into the scrotum.
