My dog managed to get his mouth around a hen today. He mostly got feathers, but tore a piece of skin from her back. It is still attached, like a flap. She is bleeding, but not scarily fast. I have isolated her in my bathroom (she's hiding behind the toilet at the moment). How should I clean it? I have hydrogen peroxide and neosporin handy. Should I try to sew it up? I'm not sure I have the stomach for this, but I have a good friend who would lend a hand. Thank you in advance. I can post a picture if it helps.
