Sores on Udder or Teats of Lactating Mare

Summary

Nursing mares occasionally develop sores on their teats. This is often a consequence of physical trauma, windburn or sunburn but it can also be seen in some viral conditions, most notably Vesicular Stomatitis. In some cases, sores can be painful enough to cause a mare to not allow a foal to nurse. This can quickly develop into a serious veterinary emergency for the foal.

Assess your mare's general health using the Whole Horse Exam (WHE). Assess the mare's mouth (wear gloves), looking for ulcers inside the mouth. Contact your vet with your findings and concerns.

Your vet may suggest that you apply an udder balm to soothe the irritated skin, however this may interfere with nursing. If there is any concern about the foal, your vet may want to examine it too.
