The wound is scabbing over now. The spot that he got hurt in is where the end of the nose piece of the fly mask sits. The chain link fence is too high for him to reach the top, but yes it is rounded. He is allergic to fly's that is why his left eye is swollen and he needs fly masks, and that is only because it is the worst for Shaggy on his face. I do think asking the vet what Shaggy can use instead of fly masks is a great idea, I didn't cross my mind to do so. The only real trouble I am having now with Shaggy is getting the ointment SWAT on his face because he keeps moving his head away, no matte how gentle I try to be with him.
