My 12 week old puppy has been peeing blood for about five days now. has been seen by the vet twice, is taking liquid clavamox antibiotic and a muscle relaxer to ease the urge to strain and urinate so often. She is still having a LOT of dark red color in her urine and the relaxer doesn't seem to be helping. She is on day five of clavamox, day two of relaxer. They seem to think it's a bladder infection, what other causes could this problem be coming from? flushing with water all the time, feeding 1/3 cup food (Blue brand) 3 times a day with warm water on top of it, clavamox twice daily, aminopentamide hydro sul. (it's abbreviated) .2 mg pills, split in half twice a day. She is still very playful, happy, but is literally peeing small amounts up to ten times an hour at times. Has another vet appt tomorrow am.
