Pedigree and Respiratory Function Data for Pugs, Bulldogs, and French Bulldogs

UK Royal Kennel Club data for over 4,000 dogs analyzed by Joanna Jadwiga Ilska. The dataset includes pedigree records and Respiratory Function Grading Scheme (RFGS) results from standardized exercise tests conducted since 2019. It was last updated in May 2026.

Use Cases

• Estimate heritability of respiratory function based on RFGS grade data.
• Assess genetic correlations between traits like nostril stenosis and overall respiratory health.
• Analyze participation rates in health screening schemes across registered dog populations.
• Model the feasibility of selective breeding programs targeting Brachycephalic Obstructive Airway Syndrome (BOAS).

Strengths

• Includes data from over 4,000 dogs, providing a substantial sample size.
• Contains standardized RFGS grades from exercise tests implemented in 2019.
• Heritability estimates for key traits (0.21–0.49 for RFGS grade, 0.31–0.39 for nostril stenosis) are provided in the source study.

Limitations

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