The British Veterinary Association (BVA) and The Kennel Club in the UK (TKC) have joined together to run a hip scoring scheme for breeders, in order to test for canine hip dysplasia, the most common inherited joint problem of large breed dogs. This current system came into effect in 1984.
Dogs are scored from the age of 12 months, and can only be scored once in their lifetime.The BVA/TKC publish a list of Breed Mean Scores (BMS) for each breed, together with the number of dogs tested to date and the range of scores achieved. It is then recommended that breeders ensure their breeding stock have scores which are well below the BMS.
From an x-ray taken at the owner's vets, the BVA scores each of the hip joints: the norberg angle (0-6); subluxation (0-6); cranial acetabular edge (0-6); dorsal acetabular edge (0-6); cranial effective acetabular rim (0-6); acetabular fossa (0-6); caudal acetabular edge (0-5); femoral head and neck exostosis (0-6); femoral head recontouring (0-6), thus each hip can receive a maximum score of 53 and overall score of 106. The lower the score the better, so 0/0 would be perfect, while 53/53 would mean that the dog had no hips at all!
Norberg Angle
Measures two features  the degree of congruence between the FH and acetabulum and the length of the CrAE which gives a relative indication of acetabular depth.
Subluxation
Evaluation is based principally on the degree of congruence between the femoral had and acetabulum. The general 'fit' of these two components is assessed by the relationship between the FHC and the underlying image of the DAE; the configuration of the cranial joint space is also taken into account, particularly at the lower end of the scoring scale, when abnormalities are relatively minor. The cranial joint space is seen as a radiolucent shadow between the CrAE and adjacent cranial articular margin of the FH. For a zero score the FHC must be medial to the DAE and the cranial joint space uniformly narrow, with the curve of the CrAE eactly following that of the FH.
Cranial Acetabular Edge
Minor alterations in the shape, contour and possibly the length of the CrAE are generally believed to be indicators of poor articular congruence, while more severe changes are clearly consequences of chronic instability, abnormal marginal wear and remodelling of the joint. For a score of zero the CrAE should be convex, uniformly curved and match exactly the countour of the adjacent femoral head with no lateral or medial divergence of the cranial joint space.
Dorsal Acetabular Edge
On good quality radiographs, the DAE forms a well-defined density interface which traverses the fH almost vertically and extends a little beyond it cranially and caudally. The clarity with which it can be seen is highly variable. A minor change in the contour of the DAE, which is normal slightly curved, merits a score of 1, but small localised irregularities, seen only on radiographs of exceptionally high quality, are considered to be within normal limits.
Higher scores are related to definitive pathological changes associated with degenerative joint disease (osteoarthritis), the smallest being minor exostosis, which is usually seen cranially.
Cranial Effective Acetabular Rim
The earliest detectable abnormalities of the CrEAR are either minor exostosis, usually in the form of a small, well-modelled osteophyte, or slight 'rounding off' of the junction between the CrAE and DAE, which may be seen in the presence of a non-biblabiated CrAE.
Acetabular Fossa
Detectable bone deposition in the AF is almost always associated with marked subluxation and the amount tends to increase in proportion with the increase in the other radiographic hallmarks of secondary degenerative joint disease (osteoarthritis). Objective numerical scoring of this criterion is difficult, but as changes are likely to be recorded only in dogs with a total score considerably higher than average, the importance of a high level of accuracy is diminished.
Caudal Acetabular Edge
The CaAE is the segment of the acetabulum which is subject to the widest range of normal radiographic variation. Radiographic abnormalities are scored between 0 and 5 and changes are due mainly to exostosis with signs of wear being apparent only in advanced cases.
Femoral Head and Neck Exostosis
The normal FH should have a smooth rounnnnndish profile, but the shape may vary considerably.
Recontouring of the Femoral Head
This criterion is used to record the extent to which the FH shape is altered as a consequence of instability. Thus scores are likely to be awarded only in cases in which secondary changes are well established, when remodelling occurs as a result of the combined effects of periarticular new bone formation and loss of subchondral bone following total destruction of articular cartilage.

BRITISH BULLDOG HIP SCORES
Note that these statistics have been gathered from data collected both prior to 2001 and between 2001 and october 2007.
Though well known for having very poor hips you will see that there are only records of 18 British Bulldogs being hip scored. That's only 18 in over 6 years.This leads me to assume that breeders of British Bulldogs largely have an 'ignorance is bliss attitude'. Knowing that the breed is allegedly 74% Displastic, the breeders, realising that there is a 74% chance of their British Bulldogs not being of breed quality simply don't bother to hip score their Bulldogs prior to breeding. Yes their are other numerous health problems associated with British Bulldogs. Surely more than 18 Bulldogs have been hip scored in over 6 years? It begs the question, have some people had their dogs scored by the vets in confidence and not had the x=rays sent to the B.V.A for official recording due to the results being unfavourable? This is where it becomes difficult to breed the best Olde English Bulldogges. Finding a hip scored dog is hard enough, finding someone that will let you use one for cross breeding to produce a strain of Bulldogges that will eventually take over from the British Bulldog as we now know it is even more difficult. Suffolk Bullbreeds have found three fantastic looking British Bulldogs. We will only use a dog with a comparitively good hip score for the breed. We are currently discussing this with the dogs owners well in advance of any breedings taking place.

Prevention is great for young and old dogs, cats, equine alike, building their immune system and helping combat joint related problems and eliminating pain and discomfort.
Prevention has testimonials stating that older dogs with crippling dysplasia were up and acting like pups within 3 days!!!
The most complete health nutritional product available!!!
Nat'l CH. Joshua's Ol' Southern White aka "Josh"
Josh was certified OFA Excellent at 27 months of age...supplemented daily with Prevention the following x-ray was taken of
Josh at age 11 years on Jan 18th 2008
Dr. Jim Rahn DVM took this x-ray and was absolutely astounded
at Josh's hips saying: I've never seen any breed of dog this age with hips this good. They are very tight, as if he is a 2 year old! It's obvious:
PREVENTION PLUSTM
REALLY WORKS!!!
WOW!!! FOR JUST PENNIES PER DAY YOU TOO CAN ASSURE YOUR DOG OF A LONG, HEALTHY, STRUCTURALLY SOUND LIFE!!!!
~~~~~~~~~~~~~~~~~~~~~~~~
PREVENTION PLUSTM has been the leader in producing a nutritional supplement to improve and prevent dysplasia in the canines since 1998. Now the NEW & IMPROVED formula has new and exciting advantages added to the original formula. Some of the improvements are listed below.
anti worm parasites
The herb wormwood serves as a natural de wormer while black walnut hull and myrrh extract adds the ability to inhibit the growth of bacteria, parasites and destroy viruses.
lean muscle mass
Gamma oryzanol has proven to enhance lean muscle mass, adrenal hypo-function nervous tension and helps fight free radical damage and aging.
vitamin C complex
The vitamin C complex sodium ascorbate, calcium ascorbate, acrirola cherry extract combined to make a arthritic blend of Vitamin C and promotes the production of collagen which is the cement that holds muscles together. NOTE: Acid forms of vitamin C cause joint and tissue injury. Without the right forms of vitamin C the ligiments weaken and cannot hold the joints together. Most dog formulas use the synthetic acid form of vitamin C which is also very unstable.
amino acids L-carnitine and L-histadine
The amino acids L-carnitine and L-histadine are integrated to promote energy, reduce cardiac stress, promote liver health and enhance the entire formula to better prevent and fight arthritis type conditions so often found in dogs.
bovine glandular extracts
A blend of bovine glandular extracts has been introduced in PREVENTION PLUSTM. The health of the adrenal glands is imperative to keeping down inflammation and promoting ligament integrity. The pituitary gland is an important gland that helps regulate growth and controls the secretions of other endocrine glands.
thymus gland
The thymus gland is also of vital importance to the animals immune system elevating the ability to fight infections. Included in the complex is the health of the hypothymus gland which helps keep your dog alert while providing a strong, healthy reproductive system. The improvement to PREVENTION PLUS TM makes it unmatched in the effort to provide canines with longer healthier lives.

Tired of replacing dysplastic pups?
PREVENTION PLUSTM is recommended for dogs and cats of all ages
Breeders of American Bulldogs, Rottweilers, Great Danes, German Shepherds, etc. are having great success combating canine dysplasia and joint related problems with the supplement PREVENTION PLUSTM. This supplement has been formulated to provide mega doses of the ingredients needed to ensure your pets being able to produce Collagen. In lay terms Collagen is the protein, the intercellular cement that binds tissue, making ligaments and tendons strong as well as strengthening all other structures in the body. Good quality Collagen is dependent on ascorbic acid in ample supply. Why? Ascorbic acid is absolutely essential to life and the living process. All living mammals either produce it themselves or get it from their diet, or they die within 3 months. There is absolutely no other vitamin deficiency that works this quickly. In short, ascorbic acid prevents scurvy, immune problems, combats stress, toxins and helps maintain the growth and maintenance of connective tissue. Ascorbic acid is the protector of biochemical balance in your pets body.
The Problem
Next to humans dogs and cats are two of the worst producers of ascorbic acid , producing only 40 milligrams per kilogram of body weight. Humans produce no ascorbic acid, therefore no collagen unless received in the diet. Perhaps this makes it clear why so many humans have to receive joint replacements. And still, many continue to think dysplasia is all genetic.
Imperial Sheba Girl of Joshua
OFA Excellent, UCDIII
Let’s look at the facts and use God given common sense:
Fact: Stress depletes an already low ascorbic acid output in our pets.
The Stress Factor
* Separation from mother at weaning
* Puppy shots and worming
* Cropped ears, docked tail
* Teething
* House breaking
* Obedience and conformation training
* Growing, travel, etc.
Because stress eats the low level of ascorbic acid naturally produced by your pet, the pet produces little or no collagen. As stated before, collagen is essential for healthy joints.
PREVENTION PLUSTM aids in preventing this from happening. By offering this awesome supplement, you provide more than enough vitamins, minerals and herbs for your pet to produce enough collagen in order to produce healthy joints.

Maintaining a daily diet of PREVENTION PLUSTM
Joshua Kennels says: PREVENTION PLUSTM has eliminated hip dysplasia and growing pains in our breeding program but better than that has kept the immune systems of our breeding stock strong and healthy. Because of PREVENTION PLUSTM, we are the only kennel in the world that has produced 5 back to back to back to back to back generations of OFA Excellent American Bulldogs
When Joshua Kennels started using “Prevention”
the American Bulldog breed
Breed was 80% dysplastic.
Now for 9 years we have not had one
dysplastic bulldog. WOW!!!!!
Lemuel David Miller owner of Joshua Kennels and author of
"American Bulldogs Stories, Facts and Legends"
says:
"I've been telling folks for years that Prevention really works
...now it seems
that they are starting to believe me.
Over the years we experimented with
Prevention in our breeding program.
One example:
we took a dysplastic sire and dam
and raised a litter of 12 pups .....a real no, no!!
Six pups were kept on Prevention and six were not.
At 1 year of age, all six that maintained a daily
diet of Prevention had a preliminary x-ray of excellent
while each of the other six were dysplastic.
In eight years of use we have done many experiments
