Did your vet even do a urinalysis before prescribing, and then wanting to change antibiotics? If a UTI is suspected, I always ask for the sample to be sent to a lab for culture and sensitivity. If bacteria is present the lab will be able to identify it and then run a sensitivity on the bacteria to identify which antibiotics the bacteria will be most susceptible to. My vet will often start an antibiotic after the sample is taken just for some immediate relief, but may change the antibiotic after the sensitivity report comes back.
To check for early kidney issues, your vet can also do a urine specific gravity test on the urine right in the office. The USG will determine whether your pup is able to concentrate his urine. Diluted urine is usually one of the first signs of kidney disease.
