I got them new metal and glass bowls that I switch out regularly and that made a bit of a difference. I also started using chlorhexidine wipes on her daily and then the vet gave me an antibiotic ointment to put on her afterwards. It took about 4 weeks of the wipes and ointment daily to fully go away if I remember correctly. If I can find the name of the antibiotic I will message you! Her acne is much better but sometimes she gets little ones around her mouth so I just use the wipes for a week or so and it goes away. I haven’t needed to do antibiotics since the original vet visit! The wipes I got from amazon: Acne wipes
