Why is my dog peeing blood a month after her heat cycle? Is it UTI?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | unspayed | 1 year and 4 months old | 76 lbs

Stephanie has what looks like coagulated blood in her urine. She was just treated for myiasis with antibiotics before this blood shows up about a week or two after. Could it still be UTI (urinary tract infection)? It is observed that this blood shows about a month after Stephanie has had her cycle (heat). It happened on her first cycle and this has now happened on her second cycle. Always a month after the cycle. Is it cause for concern?

These signs might be compatible with a urinary tract infection/inflammation. Stress related (idiopathic type of inflammation) infections and presence of crystals are the most common causes of it. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed again.

    Yes this is a problem as it can indicate that Grace is suffering from a UTI or bladder stones. I would take her into the vet today for a physical exam, blood tests, and urinalysis. These tests can diagnose if she does have either of the aforementioned illness and the vet can prescribe medication to treat it.
