What's damaging my coop door?

[Jgrzyosbo]

Something is ripping the trim off my coop door, and I am afraid it will break through the door. What could do this, and how can I reinforce it? Door is OSB over a 2x3 frame.

You can buy metal sheets at the hardware store.
It could be canid or racoon.

Thank you. I'll look for metal sheets.
