Hematuria is a condition which causes blood to fall into the urine, and which may indicate a serious underlying disease process. Familial hematuria (a condition in which blood in the urine runs in certain families of animals) is usually implicated in young dogs, while cancer is the usual cause in older dogs. Females are at greater risk for urinary tract infections that lead to blood in the urine than are males.
Symptoms of hematuria include blood in the urine, a sign in itself. Red-tinged urine, with or without abnormal frequent passage of urine will be evident. In patients with cancer, a mass may be palpated during physical examination. In male dogs an enlarged and/or painful prostate gland may be felt during physical examination, and abdominal pain will be evident in some patients.
Patients with a blood-clotting disorder may present with subdermal skin hemorrhages, conditions known as petechiae and ecchymoses, which appear as bruises. These discolored spots will be indicated by round, purplish, non-raised patches on the skin.
You will need to give a thorough history of your dog's health, including a background history of symptoms, and possible incidents that might have precipitated this condition. The history you provide may give your veterinarian clues as to which organs are causing secondary symptoms. Your veterinarian will perform a thorough physical exam on your dog, with a complete blood profile, including a chemical blood profile, a complete blood count, and a urinalysis. In male dogs, examination of an ejaculate sample will help to identify prostatic disease.
Differential diagnoses for blood-tinged urine will include other causes for discolored urine. The common urine reagent strip tests for blood are designed to detect red blood cells, hemoglobin, or protein. Diet will also be considered. If you are supplementing your dog's diet with vitamins or anything different from a regular kibble diet, you will need to share this with your veterinarian, since substantial doses of vitamin C (ascorbic aid) may cause false-negative reagent test strip results.
Ultrasonography, radiography, and contrast radiography may be useful in obtaining a diagnosis. If any mass lesions are indicated, a biopsy may be necessary for a definitive diagnosis. A vaginoscopy in female dogs, or a cystoscopy in male dogs will rule out neoplasia and lower urinary tract issues.
