The yeast organisms are waiting for the proper conditions to grow. They are already in the dog's ears. They are in your ears, too. They are everywhere.

Whenever your parents allow it and whenever you are old enough to clean them yourself, change them yourself, deal with infections, and deal with the pain of getting your ears pierced.
All breeds of dog can have trouble with their ears. You should keep the ears clean by cleaning the outside (only) with some cotton balls. I personally use Nolvasan Otic to flush their ears out about once a month. If you suspect there is a problem with the ears, then take your pet to your Veterinarian to have the ears checked out. The Vet will use an instrument called an Otoscope that he or she can look way down into the dog's ear canal, checking for yeast infections, bacterial infections, mites, foreign objects like a foxtail, etc.
