My female frenchie is 14 months old and has uti after uti. The vet gives antibiotics and they go away and within a week or two of finishing the antibiotic they come right back. She had a hooded vulva and we did surgery to correct and still gets uti. We sent urine in for bacteria growth but nothing grew and just finished six weeks of antibiotics and i am sure she has another uti. Has anyone had this many uti issues? I never had any uti problems with any other dogs that i have had.
