Elbow Scoring in Mastiff-Type Breeds
What elbow registries actually record for molosser and mastiff-type breeds, what a grade means for a breeding dog, and where breed-level health expectations are published.
Read analysisElbow Score Database
Research-driven certification data for canine elbow dysplasia screening worldwide
Standardizing Elbow Dysplasia Data
After 28 years of examining joints and correlating radiographic findings with clinical outcomes, I have compiled this database to address a persistent problem in veterinary orthopedics: the fragmentation of elbow dysplasia screening data across incompatible national systems. The International Elbow Working Group established guidelines in 1990, yet three decades later we still lack universal protocols.
This resource aggregates prevalence statistics, compares grading methodologies, and provides evidence-based screening recommendations for veterinary professionals and breeders committed to reducing inherited joint disease in herding breeds.

Analysis of elbow dysplasia prevalence in working dog populations, impact on service life, screening protocols for working dog programs, and management strategies to maintain operational capability.
Read analysisDatabase Methodology
This database aggregates screening results from the Orthopedic Foundation for Animals (OFA), British Veterinary Association/Kennel Club (BVA/KC), and member organizations of the International Elbow Working Group (IEWG). Prevalence calculations exclude dogs screened before the minimum age requirements established by each registry.
All breed-specific statistics are derived from official registry publications and peer-reviewed research. Where data conflicts between sources, I have noted discrepancies and provided the methodology for reconciliation.
Core Elbow Records
These foundational records stay available as a working reference: they are revisited as grading guidance, screening evidence, and breed data develop, so readers can return to the same carefully maintained starting points.
How Elbow Scores Work
A practical comparison of IEWG, OFA, and BVA/KC systems, showing where their grades align and where an international certificate needs careful interpretation.

A clear guide to screening age, radiographic positioning, sedation, and quality checks that help produce an elbow assessment suitable for certification.
