To prevent recurrence of a yeast infection, it’s important to also treat any known causes, such as allergies or an active bacterial infection. You will also want to pay more attention to thoroughly drying your dog’s ears after baths and swims.

A prescription ear-drying solution may be helpful if your dog is prone to yeast infections of the ear. Going forward, it is also a good idea to clean and check your dog’s ears regularly. Ask your veterinarian which methods and cleaning solutions you should use for healthy ear maintenance.
