Florie is a 4-year-old, spayed female Labrador-shepherd crossbred dog. Until six months ago, Florie's medical history was unremarkable. At that time, she was diagnosed with a bacterial urinary tract infection (UTI) based on the presence of hematuria and pollakiuria; she received 500 mg cephalexin orally once daily by the referring veterinarian for five days.
