Lucy is not right

When I got home last night, all was cool with Kylie. Whatever she got into, I believe, the day before, has left her system. Though, remember how Lucy didn't eat well that morning? Well, last night as I prepared their food, all the dogs ran to their crates, as is usual, except for Lucy. She just didn't. She stayed on my bed. That's odd. Then, I called her, and she did not want in that crate as that was the gross crate, so I fed her near my computer chair, and she ate so slowly. I called the vet, thinking something was wrong with her jaw- because when I touched the joint area, her jaw popped open and she started shivering again. So, we went into the vet. Vet could find nothing wrong- no fever. I was actually hoping we would find an answer to this shivering, and now, being hesitant to eat.

Well, after a clean bill of health, we went home, and chilled for the evening. This morning, I fed Lucy in a different container, in that crate, nope, would not even think of eating in that crate. So, pulled the bowl out and put it near the chair. Again, she ate very slowly- she was licking the food, not gulping it as normal. I don't know what is going on with her- seriously. She is fine otherwise. I am wondering if Lucy needs to eat away from the other dogs? Is her anxiety due to Danny coming? What the HECK is going on? I mentioned to the vet how she dug a hole in the grass to lay in while we watched other dogs work sheep- how she then curled up in a very tight ball. He wondered about false pregnancy too. I just don't know. The next step is going to have to be blood work.
