one thing i would like to point out is at least with my vet who is the most recomended in san antonio. he dosent like to do cultures for $100ish and wait 3-5 days before the results come in , when baytril cost $6 and amicacin cost $12. that being said i did ask for a culture and recived baytril until the results came in and then got amicacin that cleared it up FAST. that was the drug that the vet originaly wanted to go with
