The aim of this paper is to report a case of perineal hypospadias in a male, six-month old French bulldog, describing the therapeutic approach.

The medical records included recurrent urinary infection, presence of ectoparasites (thick) and ehrlichiosis, previously treated with doxycycline for 28 days (5 mg/kg/BID). During physical examination, the patient was bright and alert showing a good overall body condition. Temperature, pulse, respiration, thoracic auscultation and lymph nodes were within normal limits. Abdominal palpation was unremarkable. Inspection of the [...]
