I'm sorry to hear that he's taken a turn for the worse. Poor little guy looks so tired. How does the vet discern between ear infection and PT, given the symptoms are so similar? I guess you treat for the first one first? I've had success with chloropalm 250 for stubborn ear infections and even with that it sometimes took a full month of it, plus pred, to clear up head tilt and ear problems, so keep at it. I hope your little guy starts to feel better soon. They are so strong, given the things they go through. It breaks our hearts just to see them like this, but they are the ones living with these medical issues. Hugs to Butter Beans!
