Thanks for the link! I read through it last night.

Layla's happily napping on not one, but TWO blankets. But she was not happy when her daddy brought her downstairs this morning to express her and feed her and give her a pill, and he left for work and her mommy was still upstairs trying to sleep for another 20 minutes

So her mommy did not get any extra sleep today.
Last night was actually an improvement. She drank one and a half bowls of water, and she held her pee in from 5:15 until about 10:45. No leaks at all! She was full, but not overflowing full.
The vet did not call us back last night, or maybe she did, but our phone line is not working!!! Someone will be coming to fix it today. I am a little less concerned now though with the change yesterday. If we can get someone to express her starting next week, that will be great. It turns out it is a girl, not a guy lol. I guess she must be emailing from her boyfriend's account.
Anyways, Scott told me a little more on our way home yesterday about his breif talk with the vet. She was talking about how we needed to do xrays in case there were already stones and she was going to ask her veterinary community online about how to deal with this in a paralyzed dog and stuff. Scott didn't know why we needed xrays all of a sudden. She thought that we were calling because we were having the opposite problem with Layla, that we couldn't get her to pee and/or she was peeing blood. Scott was like nooooo... she is peeing ALL THE TIME. The vet said "Oh, well I thought that was going to happen" So Scott said to me last night, she thought Layla was peeing blood and she still took TWO DAYS to call us back?!
When I get a chance today I am going to send an email to Layla's vet at the university where she had her surgery and rehab. She had done a nutritional study on Layla when I was wondering about giving her extra vitamins, so hopefully she will be able to tell me something about other possible options to avoid crystals, or maybe refer me to someone else about this bladder infection and the crystals. I think we need a second opinion.
