Cannot be touched in this area beginning about fly season ending in mid summer.
Hide bleaches at this location more and more annually. Had a biopsy with no results.
Does this horse tend to be an easy keeper and be on the overweight side if not monitored?
My metabolic horse and the one that wants to head that way both do the same thing every spring; except their skin doesn't bleach out.
The kidneys and liver are somewhere in that area. I have wondered if the fresh spring grass might be connected to this event.
Now that you have brought it up, I wonder even more.
If your mare is dry-lotted and in a stall there goes my theory, but I think it's related to the spring grass which, in turn, affects the kidneys & liver and makes that area very sensitive.
My other two horses don't get that way ---- just the two that are easy keepers. If your mare is an easy keeper, this could be a silent indicator of a metabolic issue.
Just theorizing - especially since your mare is at the age where she might be in the beginning throes of insulin resistance
Hope this made sense, I'm late for morning barn chores and not explaining myself too well
