My chi, Charlie, had the same problem when I first brought him home. I had to take him to the vet and he got antibiotics and they showed me how to "safely" clean his ears. If he doesn't jerk and is still when you touch his ears you can use a Q-tip. Its only dangerous when the jerk and then the Q-tip can puncture the ear drum. There is also drops you can find them at wal-mart, pet stores, and petsmart and you just put in your dogs ears and it dissolves the ear wax, but I'd take the dog to the vet before I used it. Since it has an odor an infection is already set up in the ear and antibiotics will fight the infection. It isn't an over night or a week solution though takes about a month and I still do weekly cleanings to keep his ears free of infection. Good Luck~Marie and Charlie Chi
