We have an 11 year old male English Bulldog named Otis. Yesterday in the morning I thought I saw blood in his urine. When he first initially went to the bathroom, the urine was definitley red. I kept looking and the rest of the day it was yellow- looked back to normal. Today it was the same. We took a urine sample to the vet. There is no bacteria present but elevated red blood cells. We have to do another urine sample on Monday. Has anyone had any experience with this? I'm so nervous about it.
