Yesterday afternoon, my senior, Heidi, got into the garbage and ate several pork rib bones. At first she seemed ok, but last night didn't eat her dinner, which I didn't encourage too much. This morning, she didn't eat breakfast and doesn't seem to feel good, just laying around. She did go outside and drank some water. This isn't the first time she has gotten into bones, as she is a huge garbage fan. Is there anything I can give her that might help? What signs should I be watching for that this is going to be serious trouble? Thanks.
