Update:

Our vet wants to see Abbey first thing in the morning. First thing, as in, before she even goes potty for the morning. She would like to x-ray her with a full bladder to check it out, and then get a sample while she is there.
I'm sure it will be a fun morning, trying to let 3 dogs out to potty before I have to go, and making one stay inside, all by myself. If she doesn't make it, I at least have to get a sample for her, but she may have to go back again for x-rays.

Please keep us in your thoughts that I can do this tomorrow--it could be quite a chore, since she is always the first one out the door in the morning, and loves to go out.
