My girl had a 2 month long uti. From 3months-5months. I'll look into what medications she got. It definately got expensive having to reculture the urine. They have no clue unless they at culturing the urine. I noticed towards the end of the second month of antibiotics that she was drinking ALOT of water. I realized it was due to her kibble. I then switched her to raw and on raw they drink 1/3 the amount of water. I had no issues since & she is now 10 months. The other think that sucked was cause the uti lasted soooo long house training took forever. Good luck hopefully it clears up soon.
