Pedigree and Respiratory Health Data for French Bulldogs and Other Brachycephalic Breeds

Over 4,000 dogs were assessed using the Respiratory Function Grading Scheme (RFGS) to estimate the heritability of respiratory health issues like Brachycephalic Obstructive Airway Syndrome (BOAS). The dataset includes pedigree records and RFGS data from UK Royal Kennel Club registered populations of French Bulldogs, Bulldogs, and Pugs. It was authored by Joanna Jadwiga Ilska and last updated on May 13, 2026.

Use Cases

• Estimate heritability of respiratory function grades based on RFGS exercise test results.
• Analyze genetic correlations between RFGS grade and nostril stenosis traits.
• Assess participation rates in health screening schemes across different brachycephalic breeds.
• Model the feasibility of selective breeding programs targeting improved respiratory health.

Strengths

• Contains data from over 4,000 dogs, providing a substantial sample size.
• Includes standardized RFGS grades and pedigree records, enabling genetic analysis.
• Heritability estimates for key traits (0.21–0.49 for RFGS grade, 0.31–0.39 for nostril stenosis) are provided in the source description.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to UK Royal Kennel Club registrations.
