Does Not Drop Penis Down when Urinating


Some male horses do not drop their penis to urinate for behavioral reasons. Others have a mechanical restriction that prevents the penis from dropping normally. The result, urination into the sheath, leads to a dirty sheath (and possibly skin irritation in the soiled areas around the sheath and on the legs) but rarely causes other problems.

What To Do

Look for obvious problems by carefully assessing the sheath for swelling, growths and discharge. Take note of urine color and the urine stream (whether it is splashy or weak, etc.). Share your findings and concerns with your vet.

your vet's role

Using tranquilizers, the vet may be able to more carefully assess the health of the penis and sheath, and determine whether there is a physical restriction or not. Many vets will also clean the sheath during this examination, which may need to be done routinely for horses urinating into their sheaths.
Questions Your Vet Might Ask:
  • Have you always noticed this behavior?
  • Does your horse seem normal otherwise?
  • When did you first notice this behavior?
  • Have you ever seen the horse drop his penis down?
  • Is there swelling of the sheath?
  • What are the results of the Whole Horse Exam (WHE)?
