English Bulldog Health Testing Requirements for Stud Dogs

English Bulldogs are beloved for their distinctive appearance — but they carry some of the most serious structural health burdens of any breed. Responsible English Bulldog breeding requires extensive health evaluation.

The Bulldog Club of America (BCA) participates in the OFA CHIC program.

CHIC Requirements for English Bulldogs

• OFA Cardiac Evaluation
• OFA Hip Evaluation
• OFA Trachea Evaluation (via radiograph)
• OFA Eye Examination (CAER)
• Patella Evaluation

Brachycephalic Obstructive Airway Syndrome (BOAS)

BOAS is the most significant health burden in English Bulldogs. The breed's extreme brachycephalic conformation causes:

• Stenotic nares (narrowed nostrils)
• Elongated soft palate
• Hypoplastic trachea (abnormally small trachea)
• Everted laryngeal saccules

The OFA trachea evaluation via radiograph measures tracheal diameter relative to body size. Dogs with severely hypoplastic tracheas should not be bred. BOAS severity is directly heritable — selecting studs with better airway function is the most important health decision in English Bulldog breeding.

Cardiac Evaluation

Pulmonic stenosis and other congenital heart defects occur. Cardiac evaluation by cardiologist is recommended.

Hip Evaluation

Hip dysplasia is nearly universal in English Bulldogs — the breed's physical structure makes normal hip development very difficult. OFA evaluation provides documentation and allows breeders to select relatively better hip conformations.

Skin Fold Dermatitis

Skin fold infections occur in areas where skin rolls fold over each other (nose rope, facial folds, tail pocket, vulvar fold). No DNA test; select against dogs with extremely deep skin folds and document that folds are clean and infection-free.

Cherry Eye

Prolapse of the third eyelid gland (cherry eye) is common in English Bulldogs. Heritable component suspected; select against pedigrees with high cherry eye prevalence.

Heat Sensitivity

English Bulldogs are extremely heat intolerant due to compromised airway function. This is directly related to BOAS severity and is a serious welfare concern. Any breeding program that improves airway function improves heat tolerance and quality of life.

Summary

A responsible English Bulldog stud dog should have: OFA trachea evaluation (no severe hypoplasia), OFA cardiac evaluation, OFA hip evaluation, OFA CAER eye exam, OFA patella evaluation, and a clinical BOAS assessment. Airway evaluation is the most important health criterion in this breed. Dogs with severe BOAS, extremely small tracheas, or severely compromised airways should not be used in breeding programs.
