Canine urinary tract infections (UTIs) are usually easy to diagnose, although they frequently are diagnosed incidentally when a dog is brought in for another problem. The veterinarian will take a thorough history and perform a complete physical examination, no matter what the dog’s presenting problems are. Most of the time, the initial evaluation will involve taking blood and urine samples for routine assessment. Many UTIs are diagnosed when the urinalyses results come in, even though the dog may have shown no recognizable signs of having a urinary tract infection. The blood test results may suggest a predisposing condition or disease, such as renal disease, neoplasia (cancer) or Cushing’s Disease.
