My pitbull had this too, I thought it was staph infection because I had googled to see pictures.
She actually had pimples on her hiney from peeing in the grass and being rubbed the wrong way.. Then when she would play w/ our other puppy he would nip at her hind legs and agitate the pimples and cause them to break open a.k.a the rash. So we took her to the vet - before we knew what was wrong w/ her- and it cost us 90$ for the vet visit and a 2 week prescription on an antibiotic... But I found a cheaper way..
Whenever you bathe your dog, use an antibacterial/anti-fungal soap - leave it on for about ten minutes..and rinse and that's a lot cheaper than the vet!!
Good luck,
