    An odd groaning sound originating from the sheath can occur when a stallion or gelding trots. This is thought to be caused by tensing of the abdominal muscles causing air to be sucked into the sheath.

    This is particularly noticeable at an extended trot or animated trot as pressure is created in the sheath with stretching of the abdominal wall from increased length of stride. It is considered a normal finding. Since this sound is caused by muscle tension and pocketed air pressure within the sheath, it may or may not lessen or disappear after a sheath cleaning. Regardless, it is usually not a cause for concern unless other signs accompany it.

    In rare cases, sounds can come from deep wounds to the armpit or groin. A sucking sound can rarely be heard immediately after a horse has been castrated. In this case it is caused by air being sucked into the incisions. This is a very different sound and occurs at the walk. Most horses with large wounds to this area are not trotting.

    If you remain concerned about this observation, talk to your vet.
