I didn't see a condo yet today so I'll post this here. In response to your PM asking me to look at Jessica's labs and U/S findings, I think her labs just show her to be a little dehydrated but she does have a high white cell count indicating some infection.
The U/S also indicated urinary tract changes. I thought it was interesting the vet did not fully discuss how the kidneys looked....were they hyperechoic indicating a kidney infection? I think I would seriously discuss with my vet that a long term antibiotic might be needed here to address a possible kidney infection. Typically, 4-6 weeks with baytril is needed. As I've indicated before, just because the culture and sensitivity did not grow bacteria does not mean a kidney infection might not be present. Gus has never had bacteria on the C&S but has had three kidney infections.
I'm also concerned about the intestinal findings. It's also odd he did not say any more about that other than "gastrointestinal disease". I would be concerned about the nodules on the liver and also the changes to the lymph nodes as well as thickening of the intestines. I'd discuss with my vet the possibility of inflammatory bowel disease but also lymphoma.
There is something going on and they need to find it. They might suggest exploratory surgery....I'm not a big fan of that but it's your decision.
Please keep us posted.
