Case Description- In the present study, a seven-year-old German shepherd female dog was referred to Veterinary Hospital of Shahid Chamran University of Ahvaz, with a two-week history of intermittent lameness and lumbosacral pain.Clinical Findings- On general examination, the vital parameters were within normal limits. A ventrodorsal (VD) radiograph of the pelvis and lumbosacral spine was taken and asymmetric lumbosacral transitional vertebra (LTV) type-۳ was diagnosed. The authors describe a case of LTV in detail, on the basis of the clinical and radiological findings.Treatment and Outcome- In the present study, we suggested surgery (laminectomy), but the owner requested euthanasia for the high-cost of medical care.Clinical Relevance- Lumbosacral transitional vertebra is a heritable disease that is frequently diagnosed in German shepherd dogs. This disorder is a risk factor for the development of vertebral instability and cauda equina syndrome (CES). This condition is thought to have clinical significance and should be selected against in breeding, especially in the German shepherds. It should be considered not to use these dogs as working dogs.
