Chiquis likely is suffering from a bacterial dermatitis in this area or possibly a yeast infection. You will need to keep her from licking by placing a cone/e-collar on her. I suggest you make an appointment with your vet for an exam. The vet will likely take a swab and check the material under the microscope to verify that this is indeed a bacterial infection or a fungal (yeast) infection and them prescribe the relevant antibiotic or antifungal medication.
