We use and recommend Blue Power Ear Cleaner.
Ingredients are alcohol (but we use witch hazel), boric acid powder and purple gentian violet solution.
Blue Power Ear Cleaner is easy to use, and does not sting or burn the dog's ears.
It works like a charm on yeast infections, even chronic infections, and plain old dirty ears. It does not kill ear mites, though.
If you have struggled to resolve ear issues with no luck, Blue Power Ear Cleaner is exactly what you need!
Search the internet for 'Blue Power Ear Cleaner' and easily find the exact recipe, but it's kind of a hassle.
