What Antibiotics Are Given to Dogs With a UTI?

Urinary tract infections (UTI) can affect dogs in a number of different ways. According to Pfizer Animal Health, this is a common infection for dogs, and as it is a bacterial infection antibiotics are needed to treat it. Symptoms of a dog UTI include difficult or increased frequency of urination; increase in thirst; pus, blood or crystals in urine; or pain in the lower back. A dog exhibiting these symptoms should be taken to the veterinarian in order to get a proper diagnosis, and to get antibiotics prescribed to treat the UTI.

  1. Primor

    • Primor is a dog antibiotic that is used to treat three different conditions: UTIs, skin infections and soft tissue infections. It is made out of potentiated sulfonamide, sulfadimethoxine and ormetoprim. This antibiotic tablet is given to dogs once every 24 hours and can be used up to three weeks.

    Naxcel

    • Naxcel is ceftiofur sodium injected once a day for the treatment of UTIs in dogs. It is used for rapid treatment of UTIs, as the direct injection gets the antibiotic into the blood stream quicker than tablets. Naxcel can be used for a treatment period of up to two weeks.

    Zeniquin

    • Zeniquin is a broad spectrum antibiotic made out of fluoroquinolone. It is used for a number of infections in dogs, including UTIs and infections in skin and soft tissues. It is given once a day in tablet form, with multiple sizes designed for different sized dogs. Zeniquin is given for up to 10 days for UTIs.

      Because this drug has been shown to cause deterioration in the cartilage of weight-bearing joints in younger dogs, Zeniquin is not recommended for small and medium breed dogs under 8 months, large breeds under 12 months and giant breeds under 18 months of age, according to Pfizer Animal Health.
