I once had a filly spook, rear, and hit her head backing out of a trailer. She suffered the same type of facial wound as the horse in this pitiful story.
It took me a year of doctoring for that wound to fully close, heal, and scar. But shoot, she was the sweetest and prettiest little thing. I still miss her.
That pit bull's attack was about as "trivial" as the bushel of proud skin the horse's owners will be picking off that wound for the next year.
