Best Home remedies for puppy acne?

I agree with the listerene. You can also put a teaspoon of apple cider vinnigar in the water once in a while, but if she's not just getting ito n her chin, I'm wondering if maybe it's an allergy to food or something besides bacteria in the drinking water. Be sure to wipe off her mouth after each meal and TRY to remember to do so after drinking. What kind of food are you feeding her? Anything with corn, soy, bi products, dyes, etc...can cause severe skin irritation and allergies in danes.
