The most common cause for hair loss and itching in this particular area is flea allergies. I would recommend that you have Shi Shi examined by a vet. The vet will examine all of her skin and discuss her medical history. The vet may need to take a sample of the skin for examination under the microscope. Once they have a better idea as to the cause, as in fleas or flea allergies, mites, or bacterial infection, they can recommend an appropriate treatment plan. https://www.petcoach.co/article/flea-allergy-dermatitis-or-flea-bite-hypersensitivity/
