Causes of Blood in Dog Urine
There are many reasons why there may be blood in a dog’s urine, including:

Some causes for bleeding in the upper urinary tract in dogs include:
If your dog is urinating blood, one or both of your dog’s kidneys could be infected.
While uncommon, kidney stones can affect one or both kidneys resulting in the presence of blood in the urine.
Idiopathic Renal Hematuria
The term “idiopathic” means unknown, so this condition describes an unknown cause for blood in dog urine originating in the kidneys.
Causes could be due to medications, a kidney infection, or immune system issues.

Kidney cancer in dogs is rare, but it does happen, and can be a cause for there being blood in your dog’s urine. This cancer is a type of cancer that can either be in the kidneys or spread to other parts of the body.
The term “telangiectasia” refers to a condition where multiple small blood vessels are dilated in the kidneys.
Certain breeds, such as Welsh corgis, have a genetic predisposition to this issue, which can lead to blood in the urine.
Lower Urinary Tract Causes
The lower urinary tract includes the bladder and the urethra (the tube that connects the bladder) and allows urine to exit the body.
Causes for blood in the lower UT in dogs include the following:
Bladder stones are crystals that form in the bladder and can cause inflammation, bleeding, and potential urethral blockages. These “stones” form for a variety of reasons, including diet, genetics, or chronic infections.
A lower urinary tract infection (UTI) is by far the most common cause of blood in dog urine. It can be caused by several things, ranging from skin allergies, urethra anatomy of and hormone-related incontinence in spayed females
The symptoms of bladder cancer in dogs are similar to UTIs and can cause accidents in the house, blood in the urine, or difficulty urinating.
Intact male dogs tend to have a higher incidence of prostate problems, and prostate enlargement or infections can cause blood in the urine.
In addition to the cases above, there are some other reasons that could explain why there’s blood in a dog’s urine:
- Infectious disease (such as bacterial, viral, or disease)
- Idiopathic causes (unknown)
- Chemotherapy can cause hematuria
- Coagulopathy (this is a condition in which the blood’s ability to clot is impaired, and can cause prolonged or excessive bleeding)
- A low number of platelets or thrombocytes in the blood (a condition known as thrombocytopenia)
- Inflammatory disease or vasculitis

If your dog is urinating blood, the first thing to do is to contact your veterinarian immediately and make an appointment, or go to an emergency vet if your general veterinarian is closed.
During the appointment, your veterinarian will attempt to diagnose your dog’s condition and may conduct a urinalysis, a urine culture, take an X-ray, or ultrasound your dog’s bladder and kidneys.

How is Blood in My Dog’s Urine Treated?
Treatment depends on the specific cause of the blood, and your veterinarian may prescribe antibiotics if the issue is a UTI, but in cases where there are other issues, such as bladder cancer or bladder stones, surgery may be recommended.
Hematuria may be caused by a metabolic condition, such as excessive production of steroids by the adrenal glands, or by diabetes. Intact dogs who have a history of hematuria may have an enlarged prostate, in which case the veterinarian may recommend neuter.
Most veterinarians prescribe anti-inflammatory or pain medicine to ease your dogs’ discomfort, and may also recommend a change in diet if your dog has urine crystals or bladder stones. Nutrition is a very important approach to managing urinary tract issues in dogs, and certain prescription foods can reduce the stone formation and optimize urine pH.
