Here is a link to a homemade ear wash solution that cocker spaniel owners use. I've heard good results using it.....you might want to try? The ingredients are simple enough:
The ingredients you'll need are white vinegar, powdered boric acid, isopropyl alcohol (rubbing alcohol), and Betadine antiseptic solution. Generic versions of the Betadine are known as Povidone-Iodine, and those are fine, too. Just be sure not to use "Betadine Scrub", which is Betadine with a detergent added. What you want is "Betadine Solution" or generic "Povidone-Iodine Solution".
