Aww poor Girl, I'm so sorry you're going through this with Paisley and that she is not feeling well. I don't have any ideas or answers to what could be causing her symptoms, other than an infection, but your vet has already done many tests, and hopefully he'll find out what is causing this. I just wanted to say I hope she's okay, and feeling better soon, and I hope the antibiotics clear it up. Sending love, hugs and prayers that she is back to herself soon. Please keep us posted on how she is doing. Feel better Sweet Girl.
