She came back last night and seems herself today, nipping toes, chasing cats. Never found out the reason but she didn't have a fever. I'm glad I took her in but have no idea what the outcome would have been if I didn't do anything. She wasn't eating anything. Now she's eating Hills ID for a few days and I'm giving her pepcid and an antibiotic for a few days. Her poops are good, no vomiting.It was a $850 for all of it, a big bill, and I think she needs pet insurance now. If I did more diagnostic tests it would have been twice as much and I just don't think they would have found anything with multiple blood tests and xrays. No fever tells me a lot. 
 So I'm looking for a good dog food for her, I guess that's another thread. 
Thank you.
