Colon Infection Dog Dog Urethra Or Colon Mass Or Tumor--what Could It Be?

Dog urethra or colon mass or tumor--what could it be? - colon infection dog

The mixture of 9-year-old boxer has problems in urine for about 10 months. Infections that are not deleted. Two Utrasound found nothing - no bladder stones or cancer or anything else. Today the vet is a suite and he said he felt a mass in the intestines or urethra. I have an appointment with a specialist for a scan next week. In the meantime, could that be so? Cancer? Stones? Polyps? A few weeks ago it was "good." Please help ASAP!
