Are you sure that the original infection was really cleared up? Could she have a new infection? Can she be contained to a crate or a pen or maybe the bathroom for a while so you get a break from the destruction?
My dog had a UTI, took a course of antibiotics and got tested again, came up clean. She had high protien levels in that 2nd urine test so we had to get another test 2 weeks later to check for possible kidney issues. Just heard back from the vet and my dog has another UTI. Is it the original infection that somehow barely survived the antibiotics and evaded detection? Is it a totally new infection? Who knows? Dogs aren’t cats (and thankfully, Molly isn’t peeing on the furniture) but all that to say: it can take a few tries to clear an infection and/or root cause an issue.
