Just noticed this big divot on my horse’s right side.
I would expect something like this following a traumatic injury, but there was none. He lives in a stall and is turned out alone, so I know he wasn’t kicked in a pasture or anything. I groom this horse daily so can affirm this is new, like in the last few days.
For background, he’s a 19 yo TB and retired due to neurological symptoms. He gets mild exercise daily as well as turn out.
Any ideas?
