The terrier must present a lively, active and alert appearance.
It should impress with its fearless and happy disposition.
It should be remembered that the Jack Russell is a working
terrier and should retain these instincts. Nervousness, cowardice
and over-aggression should be discouraged, and it should always
GENERAL APPEARANCE. A sturdy,
tough terrier, very much on its toes all the time, measuring
between 10" and 15" at the withers. The body length
must be in proportion to the height, and it should present
a compact, balanced image, always being in solid, hard condition.
HEAD. Should be well balanced
and in proportion to the body. The skull should be flat, of
moderate width at the ears, narrowing to the eyes. There should
be a defined stop but not over-pronounced. The length of muzzle
from the nose to the stop should be slightly shorter than
the distance from the stop to the occiput. The nose should
be black. The jaw should be powerful and well boned with strongly
EYES. Should be almond shaped,
dark in colour and full of life and intelligence.

top slightly overlapping the lower.
NECK. Clean and muscular, of
good length, gradually widening at the shoulders.
FOREQUARTERS. The shoulders
should be sloping and well laid back, fine at points and clearly
cut at the withers. Forelegs should be strong and straight
boned with joints in correct alignment. Elbows hanging perpendicular
to the body and working free of the sides.
BODY. The chest should be shallow,
narrow and the front legs set not too widely apart, giving
an athletic, rather than heavily chested appearance. As a
guide only, the chest should be small enough to be easily
spanned behind the shoulders, by average hands, when the terrier
is in a fit, working condition. The back should be strong,
straight and, in comparison to the height of the terrier,
give a balanced image. The loin should be slightly arched.
HINDQUARTERS. Should be strong
and muscular, well put together with good angulations and
hand of stifle, giving plenty of drive and propulsion. Looking
from behind, the hocks must be straight.
FEET. Round, hard-padded, of
cat-like appearance, neither turning in nor out.
TAIL. Should be set rather
high, carried gaily and in proportion to body length, usually
about four inches long, providing a good hand-hold.
COAT. Smooth, without being
so sparse as not to provide a certain amount of protection
from the elements and undergrowth. Rough or broken coated,
without being woolly.
COLOUR. White should predominate
with tan, black, or brown markings. Brindle markings are unacceptable.
GAIT. Movement should be free,
lively, well co-ordinated with straight action in front and
1) Dogs and bitches should be entire and capable of breeding.
Dogs should be shown to have both testicles fully descended
into the scrotum.
2) Old scars or injuries, the result of work or accident,
should not be allowed to prejudice the terrier’s chance
in the show ring unless they interfere with its movement or
with its utility for work or stud.
3) For showing purposes, terriers are classified into two
groups according to their height, which are 10” to 12½”
and over 12½” to 15”.
