Do you see any signs of peck marks or stings around her eye? Usually swelling around an eye can be a sinus infection from a respiratory disease. Her nose looks clean, but have you seen any sneezing, rattly breathing, gasping, or nasal drainage. Occasionally a cyst or tumor can cause swelling. Antibiotics such as oxytetracycline or Tylan can be used to treat some respiratory diseases. Give us an update on her condition if she develops other symptoms.
