My dog has pus-filled bumps. What shampoo and how to treat them?

My dog has little pus filled lumps around hair follicles and I’ve been using an anti fungal shampoo on her, I think it’s helping but I’m unsure how long it will take to work and how much I can use the shampoo.

If it is filled with pus then you might need to use an anti-bacterial shampoo to treat a bacterial infection. You probably shouldn't be bathing more then twice a week. You could try a topical spray, like Vetericyn wound spray, and see if that helps. Otherwise, she should be examined by a vet to determine the cause and treat. She may need an antibiotic, anti-fungal, and/or other medications and your vet can prescribe. it might also be a sebaceous cyst that needs to be removed.
