Yeah, most horse owners in the Upstate and Tryon, NC area are calling bullsh*t on the findings.
If the horses were alive and standing, it could not have been hogs.
More likely panther/mountain lion wounds.
For some reason wildlife people have great resistance to acknowledging their presence.
By the way, I have a lot of experience with horses and almost every horse I have owned was really scared of hogs.
So no horse I ever owned would stand still for a hog attack. I think if in a pasture, the horse would run through the fence to get away if the attack persisted.
I should have made my reply conditional upon the report of a high bite being correct.
We will eventually find out.
