~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 Breed Standard

General Appearance
Large, powerful, alert, with much substance and heavy bone.

Characteristic
Large, broad head, with relatively small eyes and erect ears carried forward in line with back of neck; large, curled tail, in balance with head.

Temperament
Dignified, courageous, aloof; tends to show dominance over other dogs.

Head and Skull
Large, in balance with body, skull flat, forehead broad, defined stop and clear furrow. Head forms blunt triangle when viewed from above, free from wrinkle. Muzzle broad and strong, cheeks well developed. Nose large and black, bridge straight. Lips tight and black. In white dogs flesh colour pigmentation is permissible on nose and lips. Length from nose to stop is to length from stop to occiput as 2 is to 3.

Eyes
Relatively small, almond-shaped, clean, moderately set apart and dark brown. Eye rims dark and tight.

Ears
Relatively small, thick, triangular, not low set, carried forward over eyes in line with back of neck, firmly erect. Moderately set apart; slightly rounded at tips.

Mouth
Jaws strong, with a perfect, regular and complete scissor bite, i.e. upper teeth closely overlapping lower teeth and set square to the jaws.

Neck
Thick and muscular, comparatively short, widening gradually toward shoulders. Pronounced crest blends with back of skull.

Forequarters
Shoulders strong and powerful, moderately laid back. Elbows very tight. Forelegs well boned and straight when viewed from front. Pasterns inclining at approximately 15 degrees.

Body
Longer than high, as 10 is to 9 in males, 11 to 9 in bitches. Chest wide and deep, depth of brisket is one-half height of dog at shoulder. Well developed forechest. Level back, firmly muscled loin, moderate tuck up. Skin pliant but not loose.

Hindquarters
Strong and muscular, well developed thighs, moderate turn of stifle. Strong hocks, with only moderate angulation, well let down, turning neither in nor out.

Feet
Thick, well-knuckled, very tight, turning neither in nor out. Pads hard. Nails hard. Dewclaws on hind legs customarily removed.

Tail
Large and full, set high, carried over back, full or double curl, always dipping to or below level of back. On a three-quarter curl tail, tip dips down flank. Root large and strong. Hair coarse, straight and full with no appearance of a plume. Sickle or uncurled tail highly undesirable.

Gait/Movement
Resilient and vigorous with strides of moderate length. Back remains firm and level. Hindlegs move in line with front legs, whilst gaiting will single track.

Coat
Outer coat coarse, straight, and standing off body. Undercoat soft and dense. Coat at withers and rump is approximately 5 cms (2 ins), slightly longer than on rest of body more profuse on tail. No indication of ruff or feathering.

Colour
Any colour including white brindle or pinto. Colours are brilliant and clear. Markings are well defined with or without mask or blaze.

Size
Height at withers: dogs: 66-71 cms (26-28 ins); bitches: 61-66 cms (24-26 ins).

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.

Note
Male animals should have two apparently normal testicles fully descended into the scrotum.

 Hip Dysplasia

 

The hip, or coxofemoral joint, is a  ball-andsocket joint comprising a cup-shaped socket and the head of the thigh bone or femur, which is roughly  spherical. These are held in place by soft tissues and, to some extent,  the surrounding  muscles. The term ‘hip dysplasia’   is  used to describe hip joints which are  loose and/or ill-fitting, many of which  will  develope  steoarthritis as the dog ages. In the young puppy,  the  skeleton  is  fairly  soft  and  any  laxity  or  incongruity  of  the  hip  joint  will  result  in an abnormal   conformation.   As  the  animal  matures,  this  abnormality  becomes  permanent   as  the skeleton hardens. Even following  skeletal maturity (at about one year of age) abnormal stresses on the bones and soft tissues cancontinue to cause bony remodelling and the  production of arthritic new bone.

How can hip dysplasia be diagnosed?

Certain clinical  signs  such as pain on rising or  abnormal gait can lead to a suspicion of hip dsyplasia but it must be confirmed with an Xray. However, many dogs with hip dysplasia show no clinical signs until  later  in  life,  when  arthritisas developed.  If they  have been  used for breeding, hip dysplasia genes will have been passed to their offspring. The condition is a disease which is governed partly by genetic  features  and  partly  by  environmental f actors such  as nutrition, bodyweight and exercise. Therefore, the  radiograph  simply  records  the  physical  end-result  of  a  variety  of  causes  and, at present,  this  is  the  best  tool  for  screening dogs for hip  dsyplasia. Although different assessment criteria  are  used  in  different countries,  discussions  between  interested  parties are  ongoingin  an attempt to provide some international standardisation.

How are hip radiographs taken?

Radiographs  are  taken  when  the  dog  is  lying  on  its  back  with its hind legs extended and rotated inwards  so  that  the   thigh  bones  are  parallel.  The  advantage  of  this  position  is  that  it  can  be reproduced  consistently  on  different  occasions,  although  a  number  of  other projections  may  be  employed  to  provide  supplementary  information.  Sedation or general  anaesthesia are  necessary  to  allow  accurate  positioning without the  need for  the  animal to be held. The  radiographs must be identified  accurately  with  the dog’s  Kennel  Club  registration  number,  the  date and  a  right/left marker.

What is the Kennel Club Hip Dysplasia Scoring Scheme?

In the UK an assessment scheme  is  run  under the  joint  auspices  of  the Kennel Club and the British Veterinary  Association  (BVA).  Dogs  are  radiographed  by  the owner’s  veterinary  surgeon and the radiographs are  submitted to the BVA where each film is examined by 2 veterinary surgeons from its panel  of  expert s crutineers.  Nine  anatomical  parameters  are  examined  from  each  hip  joint  and allocated  a  score, ranging  from 0 (perfect) to 112 (worst). The scoringscheme allows dogs  within  a breed to be compared with each other, and dogs should only be used for breeding if their hip score is well  below  the  average  score  for  that   breed.  It  is  also  helpful  to  consider  the hip scores of the parents,  grandparents  and  siblings  when  selecting a dog or bitch for breeding. Dogsshould only  be used  for  breeding  if  their  hip  score  is  well  below  the  average  score  for  that  breed.
