Pet's info: Dog | Basset Hound | Female | spayed | 2 years and 6 months old | 55 lbs
My dog has had ongoing UTI for 2-weeks, vet ordered ultrasound and the clinic she had to go to demanded dhlpp before seeing her, I fully planned on getting it done, I just didn't want to while she had an infection. Thankfully ultrasound normal but is vaccine still effective even though she was on amoxicillin and switched to baytril today? Also, said uterine wall thick but she was spayed at 6-months, said pribably from many UTI's.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Antibiotics will not make the vaccine not effective. The reason to not vaccinate when they are sick is that the immune system is already ramped up when you are sick, so as to not make it worse. This is more of a concern when there is systemic inflammation (whole body response) to the infection vs. an isolated infection in the bladder. A thickened wall of the bladder could very well be from chronic urinary tract infections, however the question would be WHY is she having chronic urinary tract infections. Also, before switching antibiotics (which is OK to try) it is a good idea to get a culture done of the urine to determine which antibiotic is best to use. If this course of antibiotics doesn't work, or if Gracie gets another urinary tract infection within the next year or so, then I would suggest making sure you get a culture of the urine before starting antibiotics (ideal but often not done due to cost of this test), and also I would be looking at her vulva area to determine if there is a physical cause to her getting chronic urinary tract infections. This can happen when animals are obese, or if there is a lot of extra skin or flaps around the vulva and infection is present around the vulvar skin. Sometimes doing surgery of the skin around the vulva can help prevent more urinary tract infections. Best of luck with Gracie!
