slleipnir go to ur vet & ask for some ear cleaner/drier stuff, it should be in a white plastic bottle with blue on it. If the ears seem a tad red put some in, if the dogs get wet, put some in, when u clean their ears put some in. Max had to have an operation cause of an ear infection & we were told to give him lots of the stuff. & Max hasn't had problems since & when little ones start up, we give him some once a day untill the red is gone & poof he's ok.
