As with hip dysplasia there is “abnormal development” this time within the elbow joint however that is where the similarity ends as there are several different disease processes that are collectively termed ‘elbow dysplasia’.

Elbow dysplasia mostly affects large and giant breed dogs but this condition cannot be ruled out being found in other breeds.
The symptoms of elbow dysplasia include:
