My dog found a turltle in the backyard today. My dog put a hole in its shell. It looks like a red slider but not sure. I think it was hibrnating in the ground and then when we dig up the backyard friday he must of came up. I didn't notice him till tonite when my dog had it in its mouth. What can I do for it? Can I use alchole on it. Please help
