I have a mare that likes to essentially mutilate herself by itching until it bleeds. Presents sort of as a summer sore, but since they literally pop up overnight, they are not. She also had some proud flesh sawed off about a month ago that is maybe a third the size as it was, but not healing in a timely manner to say the least. She’s got some funky skin and is super slow to heal– her wound she gave herself in September is still not healed, even with daily care.
