Those could be caused by bacterial infection of the skin. Bacterial folliculitis can have this kind of presentation and be present in areas of the body where there are skin folds (like armpits). Ideally a check up at your local veterinarian to confirm this clinical suspicion and antibiotic treatment would be necessary.
