I have a dog with re-occurring ear infections. The vet gave me a prescription and it worked for awhile. Even thorough cleaning and drying they kept coming back. We used some of the vet's monthly and then weekly medicines. It would keep them at bay but eventually would flare back up. I was spending some $$$ back and forth. I met this holistic pet owner and she gave me the following recipe with this explanation. 16oz. of isopropyl alcohol, 2 teaspoons of boric acid and 10-12 drops of gentian violet (1%). The alcohol served as a carrier and readily evaporates. The boric acid lowers the ph to prevent further growth. The genetian violet serves as a topical. I used it. 5-7 days of daily usage cleared the last one. A weekly squirt in each ear. It has been over a year since he had any ear issues. Ever heard of such a concoction? EWO
