Tango had the same thing at one time and we went a different route than giving him allergy meds(some of which can have long term effects on the organs) I clean his ears every 3 days with dermapet cleaner. I also keep some otomax and tresaderm on hand and alternate between them every few weeks. His were so bad that he ended up with a hematoma(sp) and had to have surgery to fix it. This has been the solution for us and we have no more torn looking ears..no bloody head and no bloody walls. Might be something to look into instead of allergy meds for life. I'm not certain what kind of shots or meds your giving but i'd check into them and make certain they arent harming the kidneys . I know predisone(sp again) can cause damage over a period of time. Just some info from one who suffered thru it too. Good luck!
