How long should a 4 month puppy be off of an antibiotic prior to a urine culture? We are visiting a specialist for an UTI after three courses of antibiotics.

In general, a dog should be off antibiotics for 10-14 days prior to a urine culture, but sometimes we will culture a dog that has not been off antibiotics that long if we suspect that there is still an infection. I would certainly discuss that with the specialist and get their recommendation. I'm so sorry that you are dealing with a challenging problem in such a young puppy, but I hope the specialist is able to help Jett. Good luck! I hope that was helpful and answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.
