The Standard

Characteristics:  

The terrier must present a lively, active and alert appearance. It should be remembered that the Jack Russell is a working terrier and should retain these instincts. Nervousness, cowardice or over aggression should be discouraged and it should always appear confident.

General appearance:

A sturdy, tough terrier, very much on ist 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 a 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 Stopp should be slightly shorter than the distance from the stop to the occiput.

 Eyes:

Should be almond shaped, dark in colour and full of life and intelligence.

Ears:

Small ´v´ shaped drop ears carried forward close to the head and of moderate thickness.

Mouth:

Strong teeths ith the top slightly overlapped 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 size hands, when the terrier is in a fit, working condition. The back should be strong, straight and, in comparison to the hight of the terrier, give a balanced image. The loin should be slightly arched.

Hindquarters:

Should be strong and muscular, well put together with good angulation and bend 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 or out.

Tail:

Should be set rather high, carried gaily and in proportion to body length.

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 marked terriers are not allowed to be shown or registered with the BJRTC.

Gait:

Movement should be free, lively, well coordinated with straight action in front and behind.

Please note:

For showing purposes, terriers are classified in two groups; 10“ to 12“; over 12“ up to 15“.
Old scars and injuries, the result of work or accident, should not be allowed to prejudice a terrier’s chance in the show ring unless they interfere with its movement with its utility for work or stud.
Male animals should have two apparently normal testicles fully descended into the scrotum.
A Jack Russell should not show any strong characteristics of another breed
