I would recommend taking Crybaby back to the vet for re-evaluation. Some dogs can have recurrent UTIs, but often they are secondary to a bigger issue, such as bladder stones, cancer, or anatomical issues. Another round of antibiotics may help, but may just cover up the bigger issue, again.

    Blood in the urine can come from the bladder or the prostate. The fact that the blood went away and then returned means that there is still a problem. The prostate can get infections, tumors and abscesses. The bladder can have bacterial resistant infections, bladder stones or tumors. The next steps would be to have a prostate exam, a urine culture with a cystocentisis and potentially an ultrasound of the bladder and prostate. Best of luck and please feel free to post any additional questions.
