Hello! I'm new to this site and looking for help from other bulldog owners who may have experience with recurrent UTIs. Our female EBD started showing signs of her second UTI since September at the end of March. She was put on 14 days of antibiotic therapy. At the end of treatment our vet brought her back in for a urinalysis which revealed that the infection had subsided but there were still red blood cells present in her urine. After speaking with the vet we decided to move forward with an ultrasound and another round of blood and urine testing. By the time we did the second round of testing the infection had returned. The ultrasound also revealed a very slightly enlarged kidney. She was put on a new antibiotic (broad spectrum) for 1 month. Our vet has been awesome and laid out a very detailed follow up plan where we brought our dog back each week for testing. Everything was looking great (no infection, kidney levels normal) until our final week of antibiotics. I got a call yesterday that the infection is back. Our next step is see an internal medicine specialist to try to seek out an underlying cause of infection. In the meantime, I'm driving myself crazy wondering what could be wrong. Has anyone had experience with a UTI that keeps returning despite aggressive antibiotic therapy? I should mention that our dog has acted completely fine since she has been on antibiotics. Luckily our vet has been extremely diligent follow up or we may have just assumed she was fine.
