Staph dermatitis symptomizes immunoinsufficiency, an immune system incapable of rising to the challenge of a normal daily microbe (like Demodex). Appropriate antibiotics are usually effective on a remedial (2 X daily for 2 wks) or maintenance schedule (2 X weekly indefinitely).
Vaccinations are typically used as a protection against viral pathogens, but an example of a bacterial vaccination is Staph Lysate. Many dogs benefit from a boost to the immune system provided by the latest formulation of Staph Lysate, very finely chopped pieces of staph bacteria. Staph Lysate should be injected on a weekly schedule for a month, then boosted monthly through allergy/staph season to remind the immune system how to effectively combat the bacteria.
