Seriously, Betty has the best advice here. Abby fought staph because of her allergies for years. Now I have the big spray bottle of Microtek and I say "Abby, want your tummy sprayed?" and she lays down, rolls over and closes her eyes in bliss. Try it and good luck!My Cody had AIHA ( an autoimmune anemia) and as a side issue had terrible staph infections. Of course, he would go thru rounds of antibiotics, but a real life saver (literally) was the Eqyss Micro-Tek shampoo. I used it several times a week and it was miraculous. It is still the only shampoo I use on my crew. You can read about it or order here. www.eqyss.com It's great for any skin issue.
