Urethral Prolapse

Key Points

Urethral prolapse is an uncommon condition found in younger dogs

A fleshy knob of tissue is found projecting from the end of the penis

This condition is corrected with surgery



  • the urethra is the tube that passes urine from the bladder to the outside of the body
  • the tube runs through the penis
  • weakening of the tissue that normally holds the urethra in place results in prolapse of the urethra


  • most dogs are younger when this condition occurs
  • it only affects male dogs
  • the most common breed affected is the Bull dog

Clinical signs

  • straining to urinate
  • licking the penis
  • irritation of the penis
  • red mass protruding from the penis
  • note the mild prolapse in the photo below

  • major prolapse in the photo below


  • surgical removal of the prolapsed urethra
  • the edges of the urethral are sutured carefully in order to prevent narrowing of the opening
  • in the photo below the urethral prolapse has been removed and sutured


  • typically the response to surgery is very good


  • recurrence of the prolapse, necessitating another surgery
  • stricture of the urethra
