Unfortunately, we are legally prohibited from providing a dose in the absence of a physical exam and VPCR (Veterinarian-Patient-Client Relationship). It is important to have a UTI diagnosed by your veterinarian. A sterile urine sample can be collected and submitted for culture and sensitivity. This may identify the organism responsible as well as the best antibiotic to use in treatment. The SMZ-TMP tabs you have may not be effective against the bacteria. Additionally, inappropriate antibiotic use can lead to resistant bacteria and may complicate any underlying condition which could delay diagnosis.

You should never give your dog antibiotics without having her checked by a vet, this antibiotics is not the antibiotic of choice for a UTI in dogs, I strongly recommend that you take her to your vet , take a fresh urine sample with you in a clean plastic container so your vet can perform a urine analysis.
