This may be local irritation or infection. If Kiely is licking at it, place an e-collar (cone) on her. Keep the area clean and dry. This may be enough to allow for healing. If the rash worsens or spreads though, she will need to be examined by your veterinarian. Antibiotics, anti-inflammatory and/or antihistamines may be indicated depending on the diagnosis.
