Pug, Female, 29 months old, spayed on 22nd April, 2015 with complete removal during her heat. After the surgery she was treated on a heavy dose of antibiotic however started loosing fresh blood after around 15 days of surgery. An ultrasound and X-Ray was conducted however no apparent issue was found in that. So she was again treated on antibiotic for an UTI. She was well for ~1.5 month however she has again started loosing blood in urine now. Mostly the blood comes at the end of urination and though it is mostly brownish clot sometime she does have fresh blood too. The urination was frequent for a day on Sunday however now it is back to normal routine i.e. twice or thrice a day. She does not seem to be straining and is perfectly active otherwise. Our vet suggests that the recent symptoms are for an UTI only and the other vet also seems to agree to our first vet. Any ideas what else we could do to search out for an issue?
