Details
Chondrodysplasia is a catagory of skeletal dysplasia leading to abnormal growth of cartilage, resulting in distinct dwarf characteristics. Even though Chondrodysplasia is normally regarded as a defect in not-short breeds, this canine mutation is not always classified as a defect, but as a short-legged phenotype that defines at least 19 dog breeds including Dachshund, Corgi, and Basset Hound.
