Short-limbed dwarfism and ocular defects in the Samoyed dog

Abstract

A syndrome of short-limbed dwarfism and ocular defects was found in Samoyed dogs. The most prominent abnormalities were small stature and valgus deformity of the carpi. Radiographic evidence of retarded growth at the distal ulnar physis was apparent by 12 weeks of age. Ocular defects included cataracts and retinal detachment. Family studies and limited breeding experiments were consistent with an autosomal recessive mode of inheritance.
