RFGS Data Summary Statistics for Brachycephalic Dog Respiratory Health

UK Royal Kennel Club registered populations of Bulldogs, French Bulldogs, and Pugs form the basis of this dataset. It contains summary statistics from the Respiratory Function Grading Scheme (RFGS), analyzing data from over 4,000 dogs alongside pedigree records to estimate trait heritability. The dataset was authored by Joanna Jadwiga Ilska and last updated in May 2026.

Use Cases

• Estimate heritability of respiratory function grades based on RFGS exercise test results.
• Assess genetic correlations between respiratory function and nostril stenosis traits.
• Analyze RFGS screening participation rates across UK-registered brachycephalic dog breeds.
• Support feasibility studies for selective breeding programs targeting improved respiratory health.

Strengths

• Includes data from over 4,000 dogs, providing a substantial sample size for analysis.
• Combines RFGS clinical assessment data with pedigree records, enabling genetic studies.
• Provides moderate heritability estimates (0.21–0.49 for RFGS grade, 0.31–0.39 for nostril stenosis) with significant genetic correlations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 9.5 KB file size suggests the dataset contains summary statistics, not the raw individual-level records.
