We made another trip to our family vet yesterday due to sudden onset complications from what seems to be a bladder infection. Around lunchtime he began having small accidents every 30 minutes or so around the house, and by our 4pm appointment they were happening every few minutes, heavily stained with blood. Had some tests to see if his kidneys or liver were failing (and the source of the blood) but they seemed to be OK, so we’re back on another antibiotic for a week with a urine retest this Friday. Within two hours of taking the first dose the accidents and the blood began to subside so hopeful this is only a small temporary setback.
