So we are treating him again with metrodinazole and he had an otic solution put in his infected ear on top of that. He costs us a fortune. 150$ today and another 230$ next week. Everything is normal with him except his gut. The vet wants to try food trial. Diet, diet, diet. Sigh. We will NEVER EVER cure his gut problems he's had ever since we got him. That is obvious. But as long as he continues to put on weight, there is hope and calm.
