My mom has been working around the house a lot lately, and I guess a nail or something metal was lying on the ground. I was working in the kitchen, and I heard a metal clink that sounded like a nail falling on the ground. But then Molly started making vomiting motions and I brought her out so she didn't puke on the floor and she started eating grass like crazy. I don't know what to do. Please help. I don't think she's thrown up at all, as I didn't see any. But if she did eat a nail, then what should I do? Is this an emergency or can I let her just puke sometime. Also, about the grass, should I let her keep eating it, or should I keep her inside. She's lying by my chair right now indoors.
