This is a follow up to my previous post on strange dog behavior. I think she is sick or something. I've got a vet appointment scheduled, but I'm still a little worried. My dog throws up sometimes, after eating, I started writing it off as "she is too hyper and she ate to fast" but sometimes im not so sure. And this past few weeks she started tipping over her food, or trying to cover it up. She just put a sock over the food, then tried to tip it over before I stopped her. I thought she was sick of my old food, so I started giving her different kinds, but she doesnt care. Could she not want to eat? What if she is sick, and she knows food makes her throw up, so she doesnt want to eat it? I'm worried.
