I keep the hair short and sniff them every day. Once a week I use an ear cleaner, a couple of drops, give em a good massage, and clean the creases with the solution on a make up pad, separate one for each ear. Dylan's ears are beautifully clean, very little wax, but Milo had quite waxy ears, got ear mites, had a terrible discharge and went deaf, poor lad, had to have drops the rest of his life as his narrow ear canals became rough. So I am quite paranoid about ears now!
