Blood in Urine

Dog with two veterinarians

Finding blood anywhere on your pet can be upsetting.  However, finding blood in pet urine can be especially alarming.  Blood in pet urine can be accompanied by difficulty urinating, or by frequent, painful urination that is released in small amounts. It can have minor causes or can be as serious as cancer.   Do peeing blood and difficulty urinating necessarily mean cancer?  No, sometimes blood in pet urine can mean much less serious issues.


Blood in pet urine can be caused by a number of different things.  Also referred to as hematuria, blood in pet urine can be the result of any type of inflammation, irritation or even because of a bruise of the animal's urinary tract.  It can also be caused by crystals or urinary stones similar to human kidney stones and by many other conditions and diseases, such as a dog UTI.   The American Kennel Club lists the following possible causes of blood in pet urine:

  • Chemotherapy
  • Clotting disorders
  • Cancer
  • Tumors
  • Estrus
  • Infectious diseases
  • Toxins, such as rat poison or onions
  • Kidney disease
  • Thrombocytopenia
  • Trauma
  • Inflammatory disease
  • Nephritis
  • Infections
  • Anatomical malformations in the urinary tract or kidney


Red blood cells can be detected visually, by simply observing while the dog urinates, or by using specific diagnostic veterinary testing.  If observing blood in pet urine prior to seeing a vet, the appearance of blood can be amber, red, orange or brown, and usually shows up when the animal urinates on a light surface, such as snow.  However, sometimes it exists, but cannot be detected without veterinary testing.

Treatments – Home remedies for immediate response

When blood in pet urine is caused by a dog UTI, there are certain home remedies that are effective for an immediate response until the dog can be seen by its veterinarian.  For instance, parsley leaf can act as an effective diuretic, or uva ursi leaf can be given for its natural astringent properties.  Juniper berry also works well for urinary tract infections in dogs.  It is important, however, that these remedies be used as short-term measures, and that the animal is seen by a qualified veterinarian as soon as possible.
