It would be best to have your dog examined by a veterinarian. Bacteria, yeast, or both can cause an ear infection. Ear mites can also cause discharge from the ears. Your veterinarian will also make sure there is not a foreign body--like a foxtail or grass awn in the ear canal. It is important to know what you are treating so treatment works. Some treatment is not appropriate if the ear drum has ruptured--your veterinarian will make sure the ear drum is intact.
Allergies often lead to recurrent ear infections. If you dog has allergies the ear infection will continue to return until the allergies are better controlled. Your veterinarian can put together a treatment plan for allergies--allergies are about control not cure.
If you know it is a yeast infection Monistat can be used topically in the ear canals--apply a small amount twice daily for 1 week.
