Why does my dog keep getting UTIs that never seem to clear up?

Updated On September 23rd, 2025

My 8 year old English bulldog has had recurring UTIS her entire life, this time for the past 3 months it doesn't seem to go away. Have done full blood work and there are no serious concerns with kidney function at this time. What could be the problem?

She should have an x-ray and/or ultrasound of her bladder to look for bladder stones. Dogs with stones tend to have chronic urinary tract infections. If your vet has already ruled out any stones than her urine should be cultured to make sure the right antibiotic is used. She may need to stay on an antibiotic for an exteneded period of time.

    In my experience, I have sedated dogs to put in a catheter, but it may not have been necessary in Polo's case. I can't say if the vet did something wrong because I wasn't there. Depending on the type of stones, there can be urinary diets he can be put on to dissolve the stones, but again that is up to his vet. You can ask his vet about it. I hope this helps.

    No , I am afraid the only thing that would make her more comfortable would be a smooth muscle relaxant and pain medicine. Either is only available from your vet. Make sure she drinks plenty and ensure that she is seen by the vet tomorrow. Your vet will want to do a urinalysis, x rays and/or ultrasound exams and blood tests to make sure the kidneys are working properly. This could just be bladder stones, but they will need to be addressed urgently as well.

    Stones in the bladder (uroliths) cause damage of the lining of the bladder, which then gets inflamed and offers a great place for bacteria to cause more damage. So the stones caused a UTI which needs to be treated with antibiotics to kill the bacteria and pain medicine to relieve the pain. Unfortunately, unless the stones are removed or dissolved (this will depend on the size and type of stones) she will keep getting UTIs. Ask your vet which type of stones Sandra has and if there is a diet to a) dissolve them and b) prevent more stone formation.
