Spayed around 2 months ago. During the 2 weeks after spay, the skin was clear and has no smell. Now the front upper half of the body and paws are itchy. Why?

Ultraviolet light on scabs and some hairs shows fluorescence suggestive of ringworm. There may be otitis externa. 

The old Chihuahua had this bald and almost hairless skin condition for a few years.  This could be due to sex hormone dermatosis in female, non-spayed dogs. The dog was spayed
around 2 months ago.

Blood test and thyroid hormone analysis are being done.  Fungal culture is being done.
