We've had our puppy for like 2 weeks now. He was peeing blood a lot so we took him to the emerg. and he got put on meds for having a UTI and the meds are almost over but he's still doing it. Sometimes he'll pee and it'll look normal, yet sometimes it just looks like pure blood. He doesn't seem to be in pain, yet sometimes he squats for a minute and does nothing. Have any of you had this problem, what do you think it could be? We have to wait another few days before we take him back into the vet.
