The authors describe a case of congenital shoulder luxation associated with swimmer syndrome in a 2-month-old english setter female puppy. Both swimmer syndrome and congenital shoulder luxation are rare growth disorders. In this particular case both disorders were present at the same time. The case was initially approached with the application of a soft bandage and then surgically, with the application of a temporary external fixator and a transarticular pin. The early diagnosis and treatment allowed the complete resolution in less than 3 months.
