Hello and thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear your pet is having an issue. By vaginal infection, I am unsure if you mean she is having vaginitis, a urinary tract infection or even a uterine infection (also called a pyometra). If she is having repeat UTIs it is a good idea to have her urine cultured and also to do some imaging diagnostics like X-rays and even an ultrasound. If she is not spayed and the infection is coming from her uterus it is very important to have her spayed as this will resolve the issue. If your veterinarian is unsure as to where the infection is coming from then the next step is urine culture and an ultrasound. In some cases a resistant bacteria is present and the culture will help rule that out. An ultrasound will help determine if there are any complicating factors like bladder inflammation, bladder stones or even cancer. More information provided by you may help us make additional suggestions. I hope this helps clear some things up for you!

HI, thanks for using Petco Pet Education Center, formerly Petcoach! The most common cause of UTIs are ascending infections (bacteria from stool gets on the vulva). If this is her first UTI, the prognosis is good. This is not contagious to you or your other pets. To prevent relapse, follow the course of antibiotics and do the recommended follow up from your Vet. I recommend rechecking the culture 7-10 days AFTER finishing all the antibiotics to be sure it is gone. If it isn't gone or she gets another infection I would check for bladder stones with an X-ray, do blood work that also checks her thyroid and be sure that your Vet checks her vulva. Sometimes there is an infection around the vulva or the vulva is recessed predisposing to re-infection and chronic UTIs. An ultrasound can also be done to be sure there isn't a bladder tumor in dogs with chronic UTIs Complications of untreated UTIs are rare but kidney infections and resistant bacteria. I wish Val the very best!
