Hello. Poor Chiquis has allergies, probably an inhalant one to pollen, grasses or dust mites. If you can get her to your veterinarian, she will have very good medications to control the symptoms. These include Apoquel & Cytopoint . You can try a hypoallergenic shampoo to help quiet her symptoms, but this will be temporary, lasting a day or so. But you can bathe her 2-3 times a week to minimize the symptoms. I would try Douxo Calm, or Hylyt antiitch shampoos, both available on Chewy.com. Also, start her on a fish oil supplement. I really recommend Nordic Naturals, also available on chewy.com, to help with the itching. Her symptoms can be controlled, but not cured unless you invest in allergy testing & a desensitization protocol, so check in with your veterinarian at your earliest convenience. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
