Subtotal traumatic penile amputation of unknown origin in a canine

Cases with a fracture of the os penis in dogs have been reported rarely, and to the authors’ knowledge, traumatic penile amputation has only been reported once. The dog presented in this case report sustained subtotal traumatic penile amputation of unknown origin. Before the presentation, the dog had been in a boarding facility, where no trauma was witnessed. The patient presented with haematuria, discharge from the prepuce, and lethargy. Upon examination, traumatic subtotal penile amputation was diagnosed, and a complete blood count revealed severe regenerative anaemia. Surgical debridement was performed, and the wound healed by second intention. During the recovery period, a urinary catheter was placed to aid in preventing urethral stenosis. Though the animal sustained extensive trauma to its genitals and subsequent anaemia, it survived with a good quality of life and acceptable urinary function.
