We brought our 8wk old English bulldog home and within days I noticed he needed to urinate often and seemed to strain to pee. At his first check up he tested positive for bacteria and blood in his urine, he was given Clavamox. At recheck 14 days later the infection remainded and he was given Cephalexin while we waited the baterial culture. The culture returned with enterococcus bacteria and his meds where changed to Amoxiciliian . At recheck today the infection remains and his urine tested high for proteins. We have already done a X-ray to check for kidney stones which was negative. Scheduled for a ultra sound tomorrow. Has anyone else had a stubborn UTI or know of something else that could be causing this infection. Frustrated that my baby has been sick for 5wks.
