Possible Causes of Blood in Urine (Hematuria):
* Urinary Tract Infection (UTI): This is a common cause of blood in urine. It can be treated with antibiotics.
* Stones (Urolithiasis): Stones in the bladder or urinary tract can irritate the lining and cause bleeding.
* Tumors: While less common, tumors in the bladder, urethra, or prostate can cause blood in urine.
* Trauma or Injury: Injury to the bladder or urinary tract can lead to bleeding.
* Kidney Problems: Kidney disease or infections can also cause blood in urine.
* Certain Medications: Some medications can cause blood in urine as a side effect.
* Coagulation Issues: Problems with blood clotting can lead to bleeding in the urinary tract.
Why Vets Might Prescribe Antibiotics:
Vets often start with antibiotics to treat UTIs, which are a common cause of blood in urine. This is because UTIs can be painful and can lead to more serious complications if left untreated.
Important Considerations:
* Multiple Vets: It's great that you've seen multiple vets, but it's important to make sure they're all aware of your dog's full history and have reviewed previous tests.
* Thorough Examination: Ask your vet to perform a thorough physical exam, including a urinalysis, blood work, and possibly imaging (like an ultrasound or X-ray) to identify the underlying cause of the blood.
* Second Opinion: If you're still concerned, it's always a good idea to get a second opinion from a different veterinarian, especially one specializing in urology.
