Hello. In a 7 month old pup, my first guess is Demodex mange. But, this could also be a simple bacterial infection. Let your veterinarian do a simple skin test to see if the mites are present. There is a very specific treatment for this & usually results in a cure within a few months. I do hope you can have her seen soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
