I'm the one who posted about benzoyl peroxide.
Yitzee must have had a staph infection like Lady had. Antibiotics only cleared it up until I stopped using them. Then the pimples came right back. I read about using benzoyl peroxide online and it has been a miracle! I get Clearasil vanishing formula and use it at the first sign of a sore.
I also use Chlorhexaderm shampoo every 4-6 weeks. Dogs naturally have staph bacteria on their skin. Staph infections are usually caused by allergies.
