My Poodle has a chronic problem with yeast infections in his ears. I am at the point where I clean them every day and it still doesn't help. I've seen several vets about it and no one has been able to offer a permanent solution. He is going to see a new vet soon who I am hopeful will help us.
I sometimes add plain yogurt to his food, which helps a little. I also recommend the powder or cream that dries their ears out. It does a great job at keeping them dry.
