Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Misty! I think the pimples are part of her skin infection. I worry that the bacterial infection may be resistant to the antibiotic she is on since she is forming new areas while on the antibiotic. I recommend calling your Vet to tell them the porgression and see if they want to change the antibiotic or recheck her. I hope this helps and I wish Misty the best!
