Luna's skin lesions look more consistent with the papules and pustules that can develop with a bacterial infection of the skin. Skin infections typically develop secondarily to allergies and can be quite itchy, which only serves to worsen an infection. At this point, Luna should go to her vet because she most likely needs a course of antibiotics to manage this condition. Also be sure that she is receiving a high quality flea preventative (such as Advantix, Nexgard or Bravecto) regularly because some dogs are allergic to even 1-2 flea bites, which can ultimately result in a skin infection. I hope that all goes well!
