Staffordshire Bull Terrier Stud Dog Guide: Health Testing, Temperament & Fees

The Stafford is one of the most loyal and affectionate breeds ever developed — often called "the nanny dog" for its extraordinary gentleness with children. Producing quality Staffords requires specific DNA testing found in no other breed.

The Staffordshire Bull Terrier is a compact, muscular terrier with an outsized personality. At 24–38 lbs, they punch well above their weight in terms of character — courageous, highly trainable, and devotedly affectionate with family. The breed has been through difficult PR — often confused with larger bully breeds — but experienced owners know the Stafford as one of the most human-oriented dogs available.

Breed-Specific DNA Tests — Non-Negotiable

Two DNA tests are required for every Staffordshire Bull Terrier stud. These are conditions specific to the breed with no parallel in most other dogs.

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

L-2-HGA is a metabolic disorder that causes progressive neurological deterioration — seizures, ataxia (wobbly gait), and behavioural changes. It is inherited recessively and is found predominantly in Staffords. Affected dogs deteriorate and are humanely euthanised early.

Every Stafford stud must be DNA tested for L-2-HGA. Clear is required or Carrier with a Clear dam. Never breed two Carriers together.

Hereditary Cataracts (HC)

Hereditary cataracts cause progressive vision loss and eventual blindness in young Staffords, often developing at 1–3 years of age. It is inherited recessively and is breed-specific in the Stafford.

Every Stafford stud must be DNA tested for HC. Clear is required or Carrier with a Clear dam. Both L-2-HGA and HC testing are offered together by most canine DNA testing providers.

Additional Health Testing

Hip Evaluation (OFA)

Hip dysplasia is present in the breed. OFA evaluation — Fair or better for a breeding male.

Eye Certification (CAER)

Annual CAER exam is standard, in addition to the HC DNA test.

Cardiac Evaluation

OFA cardiac screening is recommended for studs from lines with any cardiac history.

Temperament Standards

The breed standard explicitly calls for a dog that is highly intelligent, affectionate with people, and reliable with children. Dog aggression — while historically present in working terriers — is not a positive trait in a companion Stafford. A quality stud should be:

• Friendly and confident with strangers
• Tolerant and gentle with children
• Not aggressively reactive toward other dogs to an unmanageable degree

A Stafford that is human-aggressive should never be bred.

Stud Fees for Staffordshire Bull Terriers

Stafford stud fees typically range from $800 to $2,000:

• Health-tested male with L-2-HGA Clear, HC Clear, OFA, CAER: $800–$1,400
• KC (UK) or AKC champion with full health panel: $1,200–$2,000
• Rare colours (blue, chocolate — controversial in the breed) may see different pricing

Summary

A Staffordshire Bull Terrier stud must be DNA tested for L-2-HGA and Hereditary Cataracts — both are breed-specific and entirely avoidable with one DNA test each. OFA hip evaluation and annual CAER eye exams complete the panel. Temperament must be human-friendly and reliably gentle — the Stafford's reputation depends on it. Fees run $800–$1,500 for a well-tested male.
