How do you determine if a dog has a UTI?

To determine if a dog has a urinary tract infection (UTI), a veterinarian typically performs a physical examination, analyzes a urine sample for bacteria and abnormalities, and may conduct additional tests such as a urine culture or ultrasound. Symptoms of a UTI in dogs may include frequent urination, straining to urinate, blood in the urine, and signs of discomfort.
