Elbow dysplasia is a multifactorial condition influenced by genetics, injury, and developmental factorsโresponsible breeders consider all of these when making pairing decisions.
Elbow dysplasia (ED) is a complex orthopedic condition affecting the elbow joint, commonly seen in medium to large dog breeds. It encompasses several developmental abnormalities, including fragmented medial coronoid process (FCP), osteochondritis dissecans (OCD), and ununited anconeal process (UAP), which can lead to pain, lameness, and long-term osteoarthritis.

- Genetic predisposition plays a role in ED, but heritability varies significantly across breedsโfrom as low as 0.01 to as high as 0.36.
- Studies show that both sire and dam contribute equally to elbow health outcomes, but the risk increases when one or both parents are affected.
- Importantly, genetic correlation between left and right elbows is high, suggesting symmetrical disease is more likely to be inherited, while unilateral cases may be less genetically driven.

- Not all elbow abnormalities are inherited. Trauma, overexertion during growth, or poor nutrition can contribute to joint damage.
- Unilateral elbow dysplasia, especially when not mirrored in the opposite limb, may indicate an injury-related cause rather than a genetic one.
- This nuance is critical when interpreting elbow grading resultsโespecially in dogs with active lifestyles or those exposed to uneven physical stress.

Reputable breeders do not rely solely on elbow scores. They assess:
--- Line history: patterns of joint health across generations.
--- Pedigree depth: looking beyond parents to siblings, offspring, and extended relatives.
--- Pairing strategy: avoiding doubling up on risk factors and balancing strengths and weaknesses.
--- Contextual grading interpretation: considering whether a mild or unilateral grade could stem from injury rather than inherited disease.

- Breeders committed to long-term health use phenotypic screening, estimated breeding values (EBVs), and breed-specific data to guide decisions.
- They also educate puppy buyers about joint care, appropriate exercise, and nutrition, which can significantly influence outcomes even in genetically sound dogs.
