A. Some dirt may have got stuck inside or may have gone through the nasal cavities into the mouth/ oral cavity creating inflammation. He may be in discomfort or painful and not willing to eat for it. Monitor for the next 12-24 hours, and if he starts coughing or sneezing or if he shows signs of lethargy, depression, keeps being inappetence or even start vomiting/ retching, I would suggest to take him to your veterinarian to have him checked and have appropriate treatment.
