Here's a photo of Pepper when she had zits really badly.



They evidently weren't bad enough for antibiotics. She's had a couple of outbreaks. What we do is get a washcloth wet with warm water. Fold it up and hold it on her chin for a while to open her pores (she actually likes this). After a while, gently rub her chin with the washcloth and see if any black stuff (looks like Pepper or fleas) comes out. We did that 2 times a day for a week or so and it cleared up.

Good luck and keep us posted!
