ORIGIN: England.

COUNTRY OF DEVELOPMENT: Australia.

DATE OF PUBLICATION OF THE OFFICIAL VALID STANDARD: 08.10.2012.

UTILIZATION: A good working Terrier with ability to go to ground.  An excellent companion dog.

FCI-CLASSIFICATION:

Group     3     Terriers.

Section   2     Small Terriers.

Working trial optional.

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 do, 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, i.e. rectangular. 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 cms.

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.

Lips: Tight-fitting and pigmented black.

Jaws/Teeth: Very strong, deep, wide and powerful. Strong teeth closing to a scissor bite.

Cheeks: The cheek muscles should be well developed.

Eyes: Small dark and with keen expression. Must not be prominent and eyelids should fit closely. The eyelid rims should be pigmented black. Almond shaped.

Ears: Button or dropped of good texture and great mobility.

NECK: Strong and clean allowing head to be carried with poise.

BODY:

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. 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:

Shoulder: 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.

Forefeet: Round, hard, padded, not large, toes moderately arched, turned neither in nor out.

HINDQUARTERS:

General appearance: Strong and muscular, balanced in proportion to the shoulder.

Stifle (Knee): Well angulated.

Hock joint: Low set.

Metatarsus (Rear pastern): Parallel when viewed from behind while in free standing position.

Hind feet: Round, hard, padded, not large, toes moderately arched, turned neither in nor 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.

Colour: White must predominate with black and/or tan markings. The tan markings can be from the lightest tan to the richest tan (chestnut).

SIZE AND WEIGHT:

Ideal Height at the withers: 25 cms to 30 cms.

Weight: Being the equivalent of 1 kg to each 5 cms in height, i.e. a 25 cms high dog should weigh approximately 5 kgs and a 30 cms high dog should weigh 6 kgs.

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 and its effect upon the health and welfare of the dog and on its ability to perform its traditional work. 

  • Lack of true terrier characteristics.
  • Lack of balance, i.e. exaggeration of any points.
  • Sluggish or unsound movement.
  • Faulty mouth.

 

DISQUALIFYING FAULTS:

  • Aggressive or overly shy dogs.
  • Any dog clearly showing physical or behavioural

abnormalities shall be disqualified.

N.B.: Male animals should have two apparently normal testicles fully descended into the scrotum.

The latest amendments are in bold characters.

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.

Strong means with flat muscles. The right type should never be heavy chested.  In any of the 3 types of coat, it has been always a harsh to touch.

IMPORTANT PROPORTIONS:

The overall dog is longer than high, i.e. rectangularThe 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 cms.

Nowadays the problems we frequently find in the breed are often because of the wrong proportions. Some of the Jack Russell look more as “Mini” Parson Russell Terrier, too high in legs and too short in body. In the other hand, some of them are really too short in legs. 

BEHAVIOUR / TEMPERAMENT: A lively, alert and active Terrier with a keen, intelligent expression. Bold and fearless, friendly but quietly confident.

Soft temperament must be strictly  penalized. An aggressive temperament must be also penalized.

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.

The head is broad between the ears.

Stop: Well defined but not over pronounced.

The skull is flat. The stop is well defined but never over pronounced. You can see frequently snappy heads, and this is more notable in the smoothcoats.

FACIAL REGION:

Nose: Black.

Muzzle: The length from the stop to the nose should be slightly shorter than from the stop to the occiput.

Muzzle is not narrow.

Lips: Tight-fitting and pigmented black.

Jaws/Teeth: Very strong, deep, wide and powerful. Strong teeth closing to a scissor bite.

It’s important a well developed and strong underjaw.

Cheeks: The cheek muscles should be well developed.

The head has never to look as a cheeky look.

Eyes: Small dark and with keen expression. Must not be prominent and eyelids should fit closely. The eyelid rims should be pigmented black. Almond shaped.

Almond eyes.

Ears: Button or dropped of good texture and great mobility.

Erect or semi pricked ears must be strictly penalized.

NECK: Strong and clean allowing head to be carried with poise.

The length of the neck should be approximately 2/3 the length of the back. 

BODY:

Back: Level. The length from the withers to the root of tail slightly greater than the height from the withers to the ground.

The Jack Russell doesn’t have the proportions of the Parson, either has not to be too long.  There is something you can’t measure and you have to use the eye and see a good balance.

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. Point of sternum clearly in front of the point of shoulder.

We have to put emphasis on “chest deep rather than wide”. This means that the girth behind the elbows can be spanned by two hands. Unfortunately nowadays there are dogs with really heavy chest and this is not possible.

TAIL: May droop at rest.  When moving should be erect and if docked the tip should be on the same level as ears.

A correct tail lenght is when the tail is at the same level of the ears.

LIMBS

FOREQUARTERS:

Shoulder: 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.

Forefeet: Round, hard, padded, not large, toes moderately arched, turned neither in nor out.

HINDQUARTERS:

General appearance: Strong and muscular, balanced in proportion to the shoulder.

It’s very important to have a balance between front and rear.

Stifle (Knee): Well angulated.

Hock joint: Low set.

Metatarsus (Rear pastern): Parallel when viewed from behind while in free standing position.

Hind feet: Round, hard, padded, not large, toes moderately arched, turned neither in nor out.

Never opened. Cat feet.

GAIT / MOVEMENT: True, free and springy.

True: Straight for and back. Hocks parallel.

Free: Good reach and drive with correct extention.

Springy: Movement must show effortless and fluidity. An extended trot.

COAT

Hair: May be smooth, broken or rough.  Must be weatherproof.  Coats should not be altered (stripped out) to appear smooth or broken.

Harsh to the touch. Even if it’s not a breed known as double coated, some undercoat should be anyway present.

Colour: White must predominate with black and/or tan markings. The tan markings can be from the lightest tan to the richest tan (chestnut).

White must be at least more than 51%.

SIZE AND WEIGHT:

Ideal Height at the withers: 25 cms to 30 cms.

Weight: Being the equivalent of 1 kg to each 5 cms in height, i.e. a 25 cms high dog should weigh approximately 5 kgs and a 30 cms high dog should weigh 6 kgs.

It’s important to remember that we are talking about a small dog, well proportioned, with body being 50% and legs the other 50% of total height.

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 and its effect upon the health and welfare of the dog and on its ability to perform its traditional work.

  • Lack of true terrier characteristics.
  • Lack of balance, i.e. exaggeration of any points.
  • Sluggish or unsound movement.
  • Faulty mouth.

We must ALWAYS remember when we are judging:

1)    Height

2)    The balance which is given by 50% leg – 50% body

3)    Chest circumference, not over 43 cm

4)    Weight: 6 kg

DISQUALIFYING FAULTS:

  • Aggressive or overly shy dogs.
  • Any dog clearly showing physical or behavioural

abnormalities shall be disqualified.

N.B.: Male animals should have two apparently normal testicles fully descended into the scrotum.
