For humans, blood in urine is a symptom of bladder cancer. You may want to have a full blood panel done on her along with a complete urine culture sent out that will take several days to test for bladder infection. The in-office dip tests are not as accurate.I was wondering if this is commom in girl dogs as it comes and goes with her. She is three and a half years old. I have been told to give her cranberry juice or pills?She also always seems to be alot warmer than my boy. :thanx:
