One of my 2 rescued labs, Sam, is presently being treated for an ear infection. I'm irrigating and cleaning the ear canal one/day with Epi-Otic and wiping clean with a cotton cosmetic pad. Also am applying Ottomax twice/day and giving Keflex 3X and Prednisone 1X. This may appear to be overkill but he has to have surgery in 9 days for a congenital eye defect and they want everything cleared up by then. My vet said to use the Epi-Otic no more than 7 days in a row and once the infection is cleared up to routinely clean the ears. I plan on starting a maintenance program with my other Lab, Hokie. Good Luck
