This could be due to a respiratory infection or other infection. If infection is confirmed, antibiotics may be needed. At 2 years old, Jeffrey is considered a "senior" and predisposed to developing age related changes. Consider having him physically examined by your veterinarian to diagnose and treat any infection or injury.
