Dog Peeing Blood: Causes and Urgency

Noticing blood in your dog’s urine is alarming. Blood in dog urine, called hematuria, can make pee look pink, red or brown, or leave spots on the floor or bedding. It is always worth a vet visit, and some causes are urgent.

Common causes

Emergency signs

Go to an emergency vet if your dog:

What to tell your vet

Bring a urine sample if you can collect one in a clean container. Our symptom checklist can help you prepare.

How it is diagnosed

Your vet may recommend:

Treatment

Treatment depends on the cause. Infections usually need antibiotics prescribed by your vet. Stones may need a special diet or surgery. Our vets can’t prescribe, but an online vet can help you understand urgency and next steps. See can an online vet help with a dog UTI?

In cats

Cats with blood in the urine often have bladder inflammation or crystals. Male cats can become blocked, which is an emergency. See UTIs and urinary blockages in cats.

Frequently asked questions

Can blood in dog urine go away on its own?

Sometimes signs fade, but the cause may remain. A vet check is the safest choice.

Can stress cause blood in a dog’s urine?

Stress is not a common direct cause in dogs. Infection, stones and other medical problems are more likely.
