Respiratory Function and Pedigree Data for 4,000+ Brachycephalic Dogs

Over 4,000 dogs were assessed via the Respiratory Function Grading Scheme (RFGS) established in 2019. The dataset includes RFGS grades and pedigree records for Bulldogs, French Bulldogs, and Pugs from UK Royal Kennel Club registered populations. It was authored by Joanna Jadwiga Ilska and last updated on 2026-05-13.

Use Cases

• Estimate heritability of respiratory function based on RFGS grade data
• Analyze genetic correlations between respiratory function and nostril stenosis
• Assess participation rates in health screening across different brachycephalic breeds
• Model the feasibility of selective breeding programs to improve canine respiratory health

Strengths

• Data from over 4,000 individual dogs provides a substantial sample size for analysis.
• Includes standardized RFGS grades and pedigree records, enabling genetic studies.
• 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

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 167.4 KB file size suggests a limited scope, likely containing summary or aggregated data rather than raw individual records.
