I just got my first 2 polish frizzles, so I am new to the breed. They are about 3 mo old or so. I was checking for mites in the crest, and I did find a few. Very small amount, but I want to treat right away. Someone told me frontline was ok to use..like the stuff used on dogs. That you just put a DROP in their crest? Has anyone done this, or what do you use?? Let me know asap please, I dont want to end up with and infestation..if that can happen?
