Apparently he also gashed his food open.

What do I do for this? He is limping on it, that's the only way we knew something was even wrong.
I dipped it in warm saline water--which was an interesting task alone. He wasn't a fan of that (obviously). But now I don't know what to do... Do I wrap it? Do I cut off the flaps of skin? Do I use liquid bandage? Should I use hydrogen peroxide instead of the saline water? I am just at a loss and need some advice. Today has been a really sh**ty day.
