    Breed at a glance

    SBT-pic2.jpgThe Staffordshire Bull Terrier, Staffie, originates from mastiff-type fighting dogs. It became an officially recognized breed in the UK in 1935. Todays Staffie is a loveable, energetic, affectionate and humorous dog. It is social, active and playful. Explicit fears or aggression are rare in the breed. The breed standard describes character as “Traditionally of indomitable courage and tenacity. Highly intelligent and affectionate especially with children. Bold, fearless and totally reliable.”

    Staffies seek human company and don’t do well in kennels. The dogs are at their best as pets in active families. They don’t necessarily fit in big packs. Smooth coat and compact size also make Staffies ideal pets in cities and apartments provided opportunities for daily exercise are made available.


    Key Health Conditions

    Summary: Screening for inherited cataracts and L-2-Hydroxyglutaric Aciduria (L-2-HGA) is required or recommended by every Staffordshire Bull Terrier Club. Orthopedic conditions and other eye conditions mentioned below have been reported in this breed; screening results are available.  

    • Allergies and Atopy - conditions which may require lifetime management
    • Eye conditions
      • Inherited Cataracts - DNA Test - early onset - progressive to blindness
      • Persistent Hyperplastic Primary Vitreous (PHPV), also known as Persistent Hyperplastic Tunica Vasculosa Lentis (PHTVL) - Detected in an eye exam; dogs with grades 2-6 of this condition should not be bred.
      • Distichiasis and Entropion (Eyelashes and lids)
    • Orthopedic conditions
      • Cruciate Ligament injury
      • Elbow problems
      • Patella Luxation
      • Hip Dysplasia
    • Brachycephalic Obstructive Airway Syndrome (BOAS) in some short-muzzled dogs
    • Epilepsy
    • Neurometabolic disorder
      • L-2-HGA: DNA Test -  typically an early onset, effects include epileptic seizures, "wobbly" gait, tremors, and muscle stiffness as a result of exercise or excitement. This is a progressive neurological disease; however, symptoms can be successfully managed with affected dogs potentially living a normal lifespan - severity of symptoms is variable which may affect lifespan.

    Comment: these conditions have been noted as occurring in the breed; breeding dogs should be health/behaviour tested for the conditions mentioned. See more below.

    What do caretakers need to know

    SBT-pic1.jpgWell bred SBTs are headstrong, athletic, stable, confident dogs with excellent judgment; these dogs need supervision and training. Their high energy level means daily exercise is required. The dogs require socialization when they are pups. Some may show aggression towards other dogs and may possess a strong prey drive. The dogs can jump/get over or dig under fences; and when young, the pups like to chew. The dogs are also known as "Nanny dogs" as if the pups are properly raised, they make excellent, devoted family dogs with an affinity towards watching over children. The 'estimated' lifespan of this robust breed is >10-14 years.

    US: AKC: Breed rank for Staffordshire Bull Terriers - 2021 # 75; prior year ranks were from # 80 - # 82.

    Note the steady rise in SBT registrations from 2012-2021 in France.


    Health and Longevity Statistics

    Nordic Kennel Clubs list the breed in the Breed Specific Instructions (BSI): https://www.nkk.no/getfile.php/133181-1477564079/Dokumenter/RAS-dokument/BSI-BreedSpecificInstructions.pdf

    Areas of risk in the Staffordshire Bull Terrier are:

    1. Mouth: Lower canine teeth going up into the roof of the gum.
    2. Breathing problems. For further information, see Appendix 2.
    3. Coat and skin: Sparse coat and skin irritation.
    Look for a correct bite, normal breathing and healthy skin


    Agria - Swedish Breed Profiles

    CONTEXT: For many years, Agria Animal Insurance, Sweden (Agria Djurförsäkring, Stockholm, Sweden) has supported veterinary research and provided statistics on diagnoses for health and life claims to Swedish breed clubs. See Breeds with Swedish Insurance Data and Agria Breed Profiles (where breeds are compared to All Breeds)! We recommend that you download the Agria Breed Profiles for the Staffordshire Bull Terrier and study them for full available information. Some excerpts are shown below! The great benefits of the Swedish insurance data are that they include almost 40% of the national population of dogs, so are very representative; note that animals at very old ages are likely under-represented. Most importantly, information is available on all insured dogs, not simply those who get sick or die. This allows calculation of population-based rates (expressed as events per 10,000 years-at-risk) as well as risks and proportions. Statistics are presented as overall morbidity (rate of one or more veterinary care events [VCE]) or mortality (death), by general diagnostic categories, and by specific diagnoses.

    Staffordshire Bull Terrier: 2006-2011 2011-2016

    The top three causes of Staffie deaths in 2011–2016:

    1. Locomotor (elbow dysplasia/dystrophy/degeneration)
    2. Immunological (allergy/atopy)
    3. Injury

    The four main reasons for veterinary care in Staffies in 2011–2016:

    1. Digestive (vomiting, diarrhea, gastroenteritis)
    2. Locomotor (pain and other symptoms, elbow, spine, knee/patella)
    3. Injury (skin, claw, knee, fracture/trauma skeletal)
    4. Skin (trauma, tumours, otitis, dermatitis/pyoderma/folliculitis, allergy/atopy, itching)

    Notes: knee injuries are often cruciate ligament ruptures which have a heritable component and are something to consider when breeding.

    Extracts from Veterinary Care Events Agria 2011-2016

    Relative Risk Morbidity of Staffordshire Bull Terrier compared to All Breeds: 1.25 (The risk in the breed is 1.25 times as high than for All Breeds.)

    Finland: Mortality Data 2012-2021

    The average life expectancy according to the Finnish statistics is 10 years 1 month. The most common specified causes of death are tumor, cancer (at 10 years 5 months on average) and high age (13 years 6 months).

    Worth noting: that although deaths due to cancer are high, the average age at death is relatively high (compared to some other high cancer breeds).

    HGTD DNA Tests for Staffordshire Bull Terriers

    The Harmonization of Genetic Testing for Dogs (HGTD) Basics: The HGTD Searchable Database - Search by Breed, Search by Disease / Test and Search by Genetic Test Provider (GTP) / Lab + Genetic Counselling Resources. HGTD catalogs information provided voluntarily from genetic test providers (GTPs) including information on their company and services, quality measures and expertise, tests offered and more. As of January 2021, the HGTD Database includes 82 academic and commercial genetic test providers (GTPs) in 22 countries. Our searchable genetic phenes (phenes = characteristics/genetically controlled feature) database currently holds information on 300+ phenes across all breeds/types and provides information on each phene: links to the Online Mendelian Inheritance in Animals database (OMIA), gene + mutations, a simple and advanced disease description, inheritance details, links to original publications, patents/licenses, comments from the original researchers/experts on application, and breed specific information (such as research/validation) - where possible. Breed Relevance Ratings (BRR) support evidence-based usage and application of genetic tests. The HGTD database relevance rating indicates the level of available evidence supporting the application of a specific genetic test for a specific breed/type. Currently, the relevance rating is based on a wide variety of evidence sources. This includes peer-reviewed research papers, recommendations from the original researchers/test developers, input from additional experts including veterinary specialists, and breed experts. It is hoped that, by being more informative about what we currently know or do not know about a specific test for a specific breed, that dog health advisors and owners can make more informed decisions. Remember, this Breed Relevance Rating is not everything we need to know about the disease or characteristic; it is focused on the genetic test.

    HGTD Staffordshire Bull Terrier

    Summary

    Generally considered a robust breed, there are a small number of important breed-specific genetic tests for the SBT and a handful of trait tests that may be important, particularly for breeding considerations. Where possible, I have noted when a specific test is a common requirement or recommendation by breed clubs. Some of the genetic tests are broadly associated with “bully” breeds, and may have associations with undesirable conformation (e.g. “screw tail”). Owners or breeders of SBT crosses may also benefit from these genetic tests.

    ♦ BIG PICTURE THINKING ♦Please take into consideration - Most of the conditions with genetic tests are rare in the general population, but valuable for breeders to use to efficiently reduce risks while supporting good genetic diversity in the breed as a whole. See the Genetic Diversity section below. Also be aware that there are many DNA tests that are available for ALL breeds, that while the test itself is valid, the condition may not be a major health concern or included in health strategies for every breed. See the HGTD for a full list of DNA tests including "Trait" and "Parentage" tests.

    Test: L-2-Hydroxyglutaric Aciduria (L-2-HGA)

    BRR: green paw 20.jpg

    HSP comment: This disease can have very serious welfare impacts on the dogs, including behavioral changes, ataxia, seizures, and dementia. While not universally common, reports from breed clubs have indicated that this variant has been found in apparently unrelated bloodlines and is therefore generally recommended or required as a pre-breeding test to irradicate the risk of this condition in the breed.


    Test: Primary Hereditary Cataract (PHC)

    BRR: green paw 20.jpg

    HSP comment: This form of early onset cataract is not present at birth, and therefore can be missed by early/puppy clinical eye screening. Total blindness may occur by 2-3 years of age. This test was originally developed in collaboration with SBT breed clubs in the UK, adding additional confidence in the breed-association with this test. Thoughtful usage of this test could effectively eliminate this disease in the breed.
    In addition to this genetic test, please note that there are other breed-associated eye diseases that currently are assessed by clinical examination only.

    Test: Screw tail, Robinow-like syndrome

    BRR: green paw 20.jpg

    HSP comment: Recent research (2021) builds on the original research into the DVL2 variant that indicates not only risk for “screw-tail” and other vertebral anomalies but may also increase risks associated with brachycephalic obstructive airway syndrome and congenital heart defects. Several breeds known to be at risk for screw tail and/or having a brachycephalic phenotype were involved in the extensive studies. How common DVL2 was found in the breeds ranged from 18-50%, with a few breeds potentially fixed for the mutation. The SBT is not yet “fixed” for this mutation across tested populations. Risks of clinical disease and severity vary by breed and individual dogs. The recessive inheritance appears to vary by breed in penetrance, with some breeds having autosomal recessive inheritance and others appearing to be autosomal recessive with incomplete penetrance. Dogs who have this variant may benefit from additional breeding advice and recommendations from their genetic test provider and/or breed health specialist/veterinary specialist.


    Other breed-specific tests available, relevance unknown:
    Degenerative myelopathy, coat colour dilution MLPH-related, coat colour extension

    Comment on trait testing for the SBT:
    There are a number of coat-colour trait tests available to the SBT and in common use. It should be noted that tests for dilution, MLPH-related may also be informative of skin issues that are sometimes associated with this variant. Some of the coat colour tests also indicate coat colours and types that are commonly not to breed standard or undesirable.
