I have a Ex-Large Dog Carrier, Airline Approved. Used Once. The dog carrier is in Ashburn, Va at my daughters house. I am in need of a Large or Ex-Large Sliding Glass Doggie Door. Will do an exchange. So if someone is looking for a Ex-Large Dog Carrier who may have a Large/Ex-Large Sliding Glass Doggie Door I will barter otherwise it is $75 and in very good condition.
