A week later, we took him back to the vet, getting yet another antibiotic
after having x-rays to look for stones. She found no stones or masses on the x-rays, so she still believed it to be an infection. It still didn't go away completely but became more sporadic in the bleeding episodes. Finally, when that antibiotic was completed, the bleeding did stop for 2 weeks. Now the bleeding is back again & he is once again on antibiotics. Our vet suggested getting our dog neutered.
