Middie has always had, well.. nasty ears. I'm sorry, there's NO way to put that more diplomatically. They're gross. When he came to me he had LOADS of brown, chunky, waxy buildup.. just slathered all over them.. it was even partially on his ear-flaps and out of the canals. I cleaned them with a 10% vinegar to 90% water solution once, which got a lot of it out.. and gently wiped everything with cotton.. I've done many successive cleanings, every 2-3 weeks, but there is ALWAYS more build-up! Just tonight I took a look and he had lumps of wax down there. Urgh. (They got cleaned, don't worry. Poor guy, he hates it. He just sighs and waits patiently for ear-cleaning to be over.) They don't smell terribly good, either. Not gag-worthy or anything, just mildly unpleasant. Is there something else I should be doing for him? A better ear-cleaning solution (preferably something I can buy)?
