Maybe the first C&S got contaminated somehow and showed the wrong AB sensitivity... or they list the ABs in order maybe the vet didn't want to use the first one listed (for whatever reason).
Maybe too the food is not agreeing with her.... if she's sensitive she may do better with something else.... Usually Kidney diets do contain more salt, to get the dog to drink more, hence pee more.... and less specific minerals and junk for the kidneys to have to process out. That's why when they stop eating, they get SubQ fluids. |
