Serious post

So my dog ate a ton of chocolate on Thursday, vomited like crazy the past few days but she seemed okay. Well, when we got home today, she was on the couch, just laying there. Practically lifeless. She wags her tail, moves her legs a bit, but she doesn't get up at all. We picked her up slightly and it was as if she doesn't have a single bone in her body. She won't eat or drink anything we put in front of her. Is she... dying..?
