Snoopy unfortunately got an infection in his ears when he was 14 weeks old (now 18 weeks old) and had to have a course of treatment to clear it up, but following recommendations from our vet he now has Leo Ear Cleaner in once or twice a week, which really maintains them well, as he has a habit of putting his head in the most unwanted places, namely my muck heap at the stables, wiffy or what after that..... I haven't used Thornit but everyone on here says it the best, so would take there advice, but if in any doubt just talk to your vet they are normally very useful, I know mine our.
