Most common causes of blood in dog urine

Finding out there is blood in your Golden retriever’s blood is very traumatic for every dog owner. We’ve already explained what to do if you spot blood in your dog’s urine, but why does your dog have blood in its pee?

What are the most common causes of blood in dog urine?

Of the most common causes of hematuria is bacterial urinary tract infection. This is more common in female dogs but can occur in males too. Urinary tract infections aren’t pleasant, but they are usually treated with a simple round of antibiotics.

Urinary stones are another very common reason why dogs have blood in their pee. Stones can be found in various locations within the urinary tract like the kidneys, ureters, bladder, urethra, and their impact will depend on their location, size, number and whether they are causing an obstruction.

Other causes could include:


Traumas such as animals hit by cars can suffer various injuries, including hemorrhage within the urinary bladder.


Transitional cell carcinoma is the most common type of cancer that affects the bladder. It is most often located at the level of the neck of the bladder and leads to clinical signs such as hematuria, pollakiuria and stranguria.

Prostatic disease

Diseases of the prostate, such as prostatitis, and prostatic cancer, can cause hematuria due to its close relation with the lower urinary tract in male dogs.

Idiopathic renal hematuria

This is a rare condition where a bleed occurs at the level of one or both kidneys. The underlying cause of this condition is unknown.
