Staffordshire Bull Terrier
Breed Standard
The Staffordshire Bull Terrier breed of dog was recognized by the Kennel Club of England in 1935. This was the first official recognition of the Stafford as a Breed of dog.
But before recognition, a club had to be formed and a Standard drawn up. From John F. Gordon's book "The Staffordshire Bull Terrier" published in 1971 we have the following historical commentary found on page 39 of that wonderful publication.

MAKING THE STANDARD
Making the Standard was one of the first duties that fell to the SBTC. It was gone into thoroughly by a body of experts, men with years of experience and ownership in the breed. Two good current dogs were set up as excellent examples of the breed. They were Harry Pegg's Joe (Fearless Joe) and Mrs. J. Shaw's Jim (Jim the Dandy), the former a fawn, the latter a brindle. Their anatomy and structural points were examined, and a lot of old sketches, prints and photographs discussed. It will be understood that in any breed, provided a number of examples are available, some features will be more or less uniform or common to the majority. Assuming that these characteristics are sound ones they can then be accepted as being typical of the breed. Some difficulties were at first experienced in the discussions, for a wide range of types and sizes existed in Staffords in those days. It was natural that those who owned the big bulldoggy types claimed theirs were the right type, while those with the long-muzzled lightweights supported theirs. It needed a lot of tact and discretion on the part of club officials to convince these enthusiasts who was right and who was wrong, while still retaining their interest, to say nothing of their memberships. Clearly, the Stafford as a fighting dog had natural physical attributes expected of a combatant canine. Where these were found common to a number of dogs they were accepted as desiderata in the breed, and eventually a Standard was formulated and passed to the Kennel Club for approval. For some time argument was rife in Staffordshire towns like Walsall, Darlaston, and Cradley Heath, each of which had different ideas as to what constituted a good Stafford. However, as their opinion in the main of a good Stafford was one that fought and won, they were hardly qualified to pass worthwhile comment of any kind on what constituted a good type for exhibition.

The Staffordshire Bull Terrier breed of dog was admitted to registration in the American Kennel Club Stud Book on October 1, 1974. This was the first time that the Stafford was officially recognized in the United States as a Breed of dog. The current AKC Staffordshire Bull Terrier Breed Standard was approved November 14, 1989, and was effective January 1, 1990.
What is a Breed Standard?
A good answer to this question was given in the book "The Staffordshire Bull Terrier in America" edited by Steve Eltinge, and was as follows:

An official standard is a blueprint for a breed of dog. Every breed recognized by the United Kennel Club and the American kennel Club has a standard. Some standards (like the one for Staffordshire Bull Terriers) are simple; others (like the Great Dane Standard) contain thousands of words detailing virtually every aspect of the dog's conformation. These standards or "blueprints" describe an ideal to which breeders attempt to conform. It is the responsibility of UKC and AKC judges to thoroughly familiarize themselves with the standards for each breed that they are approved to judge. Judges must then evaluate exhibitors' dogs according to the degree to which each dog represents the Official Standard.
The Official Standard for the Staffordshire Bull Terrier, like all other standards, is written from a positive perspective. Pure-bred dog standards describe what is desirable and correct. Virtue, not fault, is emphasized. Standards mention faults as well as disqualifications but the intent is to describe the ideal. Thus, each breeder has a model or framework from which he or she may form a mental picture of the ideal dog. It is the task of the judge to grade the efforts of the breeders in attendance through a system of awards. This is a vital process for those involved in raising purebred dogs. Without standards, dog shows, and judges, the identity of all breeds would probably soon be lost.
Since there are no perfect dogs in any breed, illustrated standards are usually presented graphically. This allows the artist to selectively add the best parts of several dogs to a composite drawing. In this chapter photographs are used to illustrate the Official Standard. Although not perfect in every regard, the dogs depicted here demonstrate the ideal according to each particular section of the Standard. Photos and drawings are also used to illustrate faults.
The Official Standard for the Staffordshire Bull Terrier was accepted by the American Kennel Club in 1974. In 1975, the first Staffordshire Bull Terriers were shown in the Terrier Group at AKC shows.

South Africa and Australia both use the English Standard - both of our Kennel Clubs have the policy of using the Standard of the Country of Origin. Whatever Standard is used in the country where the breed was developed is what we use.
Whether these various different Standards in existence is a good thing, or a bad thing - well, who's to say!
The one thing that a Standard cannot describe is the intangibles of spirit, intelligence, heart and tenaciousness. The Stafford is more than the written standard and there is a lot more to him than can be seen by a show judge and his identity is more than can be seen in the show ring.
Gameness remains one of the most admired characteristics.......the Bull and Terrier breeds have the greatest degree of gameness and thus the need for a greater understanding of its origin, use, and uniqueness...... our faith is renewed and our admiration for "man's best friend" increases when our dogs are game enough to perform the duties for which they were bred!

STAFFORD HEALTH
The Staffordshire Bull Terrier, whilst a robust and generally healthy breed, can suffer from harmful and detrimental genetic diseases. Responsible breeders, with the support of the ANKC and other breeders, are attempting to selectively breed out these hereditary afflictions.
When purchasing a Staffordshire Bull Terrier from registered breeders (unfortunately not all breeders are registered with the ANKC, and generally refrain from health testing breeding stock) do not be afraid to ask the breeder about their stock, their breeding practices, nor be afraid to ask to see health certificates.
L-2-HGA (L-2-hydroxyglutaric aciduria) in Staffordshire Bull Terriers is a neurometabolic disorder characterised by elevated levels of L-2-hydroxyglutaric acid in urine, plasma and cerebrospinal fluid.
L-2-HGA affects the central nervous system, with clinical signs usually apparent between 6 months and one year (although they can appear later). Symptoms include epileptic seizures, "wobbly" gait, tremors, muscle stiffness as a result of exercise or excitement and altered behaviour.
The mutation, or change to the structure of the gene, probably occurred spontaneously in a single dog but once in the population has been inherited from generation to generation like any other gene. The disorder shows an autosomal recessive mode of inheritance: two copies of the defective gene (one inherited from each parent) have to be present for a dog to be affected by the disease. Individuals with one copy of the defective gene and one copy of the normal gene - called carriers - show no symptoms but can pass the defective gene onto their offspring. When two apparently healthy carriers are crossed, 25% (on average) of the offspring will be affected by the disease, 25% will be clear and the remaining 50% will themselves be carriers.
The mutation responsible for the disease has recently been identified at the Animal Health Trust. Using the information from this research, we have developed a DNA test for the disease. This test not only diagnoses dogs affected with this disease but can also detect those dogs which are carriers, displaying no symptoms of the disease but able to produce affected pups. Carriers could not be detected by the tests previously available which involved either a blood or urine test detecting elevated levels of L-2-hydroxyglutarate or magnetic resonance imaging. Under most circumstances, there will be a much greater number of carriers than affected animals in a population. It is important to eliminate such carriers from a breeding population since they represent a hidden reservoir of the disease that can produce affected dogs at any time.
The test is available now and information on submitting samples is given below.
Breeders will be sent results identifying their dog as belonging to one of three categories:
CLEAR: the dog has 2 copies of the normal gene and will neither develop L-2-HGA, nor pass a copy of the L-2-HGA gene to any of its offspring.
CARRIER: the dog has one copy of the normal gene and one copy of the mutant gene that causes L-2-HGA. It will not develop L-2-HGA but will pass on the L-2-HGA gene to 50% (on average) of its offspring.
AFFECTED: the dog has two copies of the L-2-HGA mutation and is affected with L-2-HGA. It will develop L-2-HGA at some stage during its lifetime, assuming it lives to an appropriate age.
Carriers can still be bred to clear dogs. On average, 50% of such a litter will be clear and 50% carriers; there can be no affecteds produced from such a mating. Pups which will be used for breeding can themselves be DNA tested to determine whether they are clear or carrier. Courtesy AHT
Hereditary Cataracts (also called Juvenile Cataracts) Hereditary Cataract in Staffordshire Bull Terriers has been recognised as an inherited condition since the late 1970’s. Affected dogs develop cataracts in both eyes at an early age. The condition is not congenital, so the lenses are normal at birth but cataracts appear at a few weeks to months in age, progressing to total cataract (and resulting blindness) by 2 to 3 years of age. The mutation, or change to the structure of the gene, probably occurred spontaneously in a single dog but once in the population has been inherited from generation to generation like any other gene. The disorder shows an autosomal recessive mode of inheritance: two copies of the defective gene (one inherited from each parent) have to be present for a dog to be affected by the disease. Individuals with one copy of the defective gene and one copy of the normal gene - called carriers - show no symptoms but can pass the defective gene onto their offspring. When two apparently healthy carriers are crossed, 25% (on average) of the offspring will be affected by the disease, 25% will be clear and the remaining 50% will themselves be carriers. The mutation responsible for the disease has recently been identified at the Animal Health Trust. Using the information from this research, we have developed a DNA test for the disease.

The test is available now and information on submitting samples is given below. Breeders will be sent results identifying their dog as belonging to one of three categories: CLEAR: the dog has 2 copies of the normal gene and will neither develop Hereditary Cataract, nor pass a copy of the Hereditary Cataract gene to any of its offspring. CARRIER: the dog has one copy of the normal gene and one copy of the mutant gene that causes Hereditary Cataract. It will not develop Hereditary Cataract but will pass on the Hereditary Cataract gene to 50% (on average) of its offspring. AFFECTED: the dog has two copies of the Hereditary Cataract mutation and is affected with Hereditary Cataract. It will develop Hereditary Cataract at some stage during its lifetime, assuming it lives to an appropriate age. Carriers can still be bred to clear dogs. On average, 50% of such a litter will be clear and 50% carriers; there can be no affecteds produced from such a mating. Pups which will be used for breeding can themselves be DNA tested to determine whether they are clear or carrier. Courtesy AHT
Persistent Hyperplastic Primary Vitreous (PHPV) - This is a congenital condition (present from birth) in which there is a developmental defect in the normal regression of some of the intraocular structures of the eye. PHPV can range from being very mild to severe abnormalities which may lead to blindness. The presence of mild abnormalities are usually seen as small brown pigmented dots on the posterior lens capsule. Previously the literature indicated that this was always observed as a bilateral phenomenon but recently it has been stated that affected dogs may show unilateral involvement, although this is less common. The present knowledge of the mode of inheritance of this disease is thought to be an autosomal irregular dominant with variable expression. Due to PHPV seldom resulting in secondary cataracts in the Stafford, those that are mildly afflicted will seldom show any form of visual impairment during the course of their lives. Even those that are more severely afflicted, may be capable of adapting by using peripheral to compensate. Stafford breeders should therefore not assume that the problem is absent simply because they have not encountered blatant signs of visual impairment, instead discerning breeders should ensure that all their Staffords are tested through the National Eye Scheme.

Distichiasis - Sometimes the condition is referred to as a double row of eyelashes, for extra hairs arise from the edge of the eyelid to rub against the corneal surface. The effects are variable and mild irritation to corneal ulceration will be seen. Treatment is extremely difficult and invariably involves surgery to remove the hair roots permanently. Plucking out the offending hairs is useful, but requires the maximum cooperation of the patient! Of course it is followed by hair regrowth, and many surgical techniques have been invented to remove the roots. Even then success is difficult to achieve, and the dog may have to suffer this condition throughout its life. It is the most common eye defect found in the Stafford in South Africa.
Entropian - Primarily an inherited condition. It is due to an excess of eyelid tissue, or a small eye, or both, the result being that a varying amount of hair-covered eyelid can turn in to rub directly against the cornea or conjunctiva, or both. It is usually extremely painful, and the damage caused to the cornea can render the eye blind. Most dogs are affected by six months of age and in some the signs of the problem (excessive blinking and a wet face) may be seen within the first month of life. Occasionally the condition is self-correcting as the puppy grows, but in the vast majority of affect dogs surgery is necessary to turn the eyelid away from the surface of the eye. Usually such surgery is successful, but it is much better that, as with the other inherited eyelid defects, breeders try to avoid producing this condition in their stock.
Hip Dysplasia - Hip Dysplasia is a terrible genetic disease because of the various degrees of arthritis (also called degenerative joint disease, arthrosis, osteoarthrosis) it can eventually produce, leading to pain and debilitation. The very first step in the development of arthritis is articular cartilage (the type of cartilage lining the joint) damage due to the inherited bad biomechanics of an abnormally developed hip joint. Traumatic articular fracture through the joint surface is another way cartilage is damaged. With cartilage damage, lots of degradative enzymes are released into the joint. These enzymes degrade and decrease the synthesis of important constituent molecules that form hyaline cartilage called proteoglycans. This causes the cartilage to lose its thickness and elasticity, which are important in absorbing mechanical loads placed across the joint during movement. Eventually, more debris and enzymes spill into the joint fluid and destroy molecules called glycosaminoglycan and hyaluronate which are important precursors that form the cartilage proteoglycans. The joint's lubrication and ability to block inflammatory cells are lost and the debris-tainted joint fluid loses its ability to properly nourish the cartilage through impairment of nutrient-waste exchange across the joint cartilage cells. The damage then spreads to the synovial membrane lining the joint capsule and more degradative enzymes and inflammatory cells stream into the joint. Full thickness loss of cartilage allows the synovial fluid to contact nerve endings in the subchondral bone, resulting in pain. In an attempt to stabilize the joint to decrease the pain, the animal's body produces new bone at the edges of the joint surface, joint capsule, ligament and muscle attachments (bone spurs). The joint capsule also eventually thickens and the joint's range of motion decreases. No one can predict when or even if a dysplastic dog will start showing clinical signs of lameness due to pain. There are multiple environmental factors such as caloric intake, level of exercise, and weather that can affect the severity of clinical signs and phenotypic expression (radiographic changes). There is no rhyme or reason to the severity of radiographic changes correlated with the clinical findings. There are a number of dysplastic dogs with severe arthritis that run, jump, and play as if nothing is wrong and some dogs with barely any arthritic radiographic changes that are severely lame.
