The specific gravity test (shows urine concentration) is important to help the vet interpret the protein finding. They really shouldn't have any protein in their urine at all. You've ruled out diabetes. The feeding of protein has nothing to do with finding protein in the urine. If it is determined to be a liver problem, then you will probably be advised to give a low protein diet because it is easier for the liver to metabolize. I think your vet will be able to pinpoint the cause of the excessive thirst by the tests he is running.
Don't really understand why you feel you should fast him - follow the vet's instructions and never withhold water from a dog you suspect might have kidney failure. |
